What do I do if QuickBooks says no account exist with that username. I was logged in a few hours ago

QuickBooks offers multiple login options for accessing your account, Dan.

You can use either your email address or your user ID to sign in. If you're unable to log in with your user ID, you have the option to use the email address linked to your account instead.

But also, please double-check that the user ID you provided is correct.
