Forgot 1password user name

So, while I'm waiting for a response to my initial question, I'll ask another. I'm having trouble with my Bank of America app, in that, 1Password won't auto load into it, except every once and a while, when the password will load, after a failed attempt to auto load the username. And if I try to copy and paste from 1Password, I can copy either the username or the password, but after pasting one of those, when I go back to copy and paste the remaining one, the original one I've pasted is gone. What's frustrating is, that at least once in the past, both the username and password auto loaded as expected. I'm using an Android S23 FE. Thanks.
