Or you know, get a password manager like the rest of us. If your password manager doesn't show the usual autofill, since the domain is different than it should, take a step back and validate everything before moving on.
Have the TOTP in the same/another password manager (after considering the tradeoffs) and that can also not be entered unless the domain is right :)
