OSU Problem

I'm using the latest version of Quicken Classic Premier.

I have an account with CIT Bank. OSU used to work with it, but it no
longer does.

I just opened a new account there, and moved all the funds from the
old account to the new one. I also have a new password for the
account.

When I choose CIT Bank for  OSU it then asks me to choose a phone
number for 2FA. I do that, but it doesn't work.  It just asks again
which number I want to use.

So I assumed that what's in the password vault is wrong. so I go to
Edit Password Vault. Under "Password Stored" it says "Not Required."
The "Add Password" button is grayed out.

I'd like to make OSU work with CUT. Can someone tell me what's wrong
and how to fix it?
