Hi there, brotherjug.

I'm here to help and provide some insights about removing an old bank account in QuickBooks Online (QBO). 

Deleting a bank account is a known issue in QBO, our engineers are currently investigating and working on an immediate fix. I suggest reaching out to our Customer Care Team to add your account to the list of affected users. This way, you’ll be notified of any updates on the progress of the investigation via email.

You can get our contact support through this link: Get help with QuickBooks Online. 

For future reference, you may also check this article on how to delete an account and restore it.

We appreciate your patience as we work through this. If there's anything else I can do for you, please let me know. I'll be around to help you out.
