That's the next step, but I cant seem to complete this portion of it I need to get the unlock code on the device before I can run that. I have tried it and it fails.

You shouldn't need a unlock code just follow the guides here.

I have a T mobile original phone so i have to append the unlock code per documentation https://support.oneplus.com/app/answers/detail/a_id/588/~/how-to-unlock-bootloader-for-oneplus-6t-%28t-mobile-edition%29[/url]. I get this error if I just try without it.

same with me ?
Try to relock and then unlock. I've had this problem too after downgrade to mm by official Huawei rollback package. Then phone and other tools shows than phone is unlocked and it was unable to flash recovery.
if it says wrong password it means you got the wrong password. it will say it's already unlocked if you try unlocking it while it's unlocked
My phone was unlocked with Potato v2.0.1, with working TWRP, rooted etc...
I solved this problem that arose after unsuccesfully install custom Rom, restore backup of stock rom, install update through dload and many many other attempts at improvement of my smartphone :-( No more time again!!!
Probably installing update through Dload will relock bootloader, but in the fastboot mode it says bootloader still unlocked.
Before I did all this, I had an original stock rom.
1: Relock bootloader with PotatoNV v2.0.1 (You need to open case and connect tespoint by wire - look on Youtube, i´ve find it there, also you need "Huawei testpoint drivers")
2: Factory reset
3: Install any update stock rom with Dload (Vol up + Vol down + power)
4: Factory reset
5: Developer options-turn on OEM unlock and USB debbuging
6:Unlock bootloader with PotatoNV v2.0.1 - keep password generated by Potato
7:Multitool 8 for Huawei - in the bootloader state unlock bootloader again - use password generated by Potato
8:Multitool 8 for huawei - install TWRP - it says "Succesfully installed" - TWRP works, root is possible. Yeah!!!
May be this is not right way to solve this, but for me it workś..

Hold volume up while connected to PC......You should enter eRecovery....From there download firmware and install
no way to connect it i tried
and when i try to get the unlock code to the bootloader in the website it gives me this error
Please make sure the verification code and model number are correct. If your device has multiple IMEIs or MEIDs, please try another IMEI or MEID.

I didn't say anything about unlock bootloader....
Just holds power and volume up button while connected to PC.......
BTW how did you end up in boot loop ?
and i just add that i couldn't unlock the bootloader and i already told you that i have access onlyn to fastboot and rescue mode bro
do you think i will be here if i could enter the recovery update
The only thing I can think of is to install Hisuite to a windows PC and try the recovery option in hi suite

Oh another thing did you register your phone to a google account?
If you did log into Google dashboard and expand the Android section it will list all of your devices and the imei so you should be able to use that to unlock the bootloader

And no I got the phone in this state so no I didn't connect it to my google account
Ok i searched for ways to find an IMEI number and found couple of ways...
1) Look under/in the sim tray. It may be there (I didn't check this out)
2) Find the IMEI/MEID using Google Dashboard. This is Google's control center that can be accessed from any computer with a web browser. You will need to log in with the Google account associated with your Android phone.You can access Google Dashboard by visiting www.google.com/settings/dashboard Expand the "Android" section by clicking the "Android" heading.Locate your phone in the list. If you have multiple devices associated with your account, all of the devices will be displayed. Find the device that you are trying to retrieve the IMEI/MEID number for. (This works)
3) At last, you can try to remove the back case and remove the battery. This can help you in 2 ways. Firstly, there should be IMEI code present under the battery. Secondly, this may cause you to get out of bootloop

What could possibly be locked at this point? I am trying to root with just magisk, don't want twrp. Is it possible?
Sure bootloader is unlocked? Does it say unlocked from the fastboot screen? You may have typed the unlock command but it may not have executed
