Welcome to the Community. I'm here to share so information about the Bank account needs attention error that you received in QuickBooks Online.
Bank account needs attention means there's a message on your bank or financial institution's (FI) website that requires action from you.
These include the following messages:
New terms of service
An announcement about maintenance or other site changes
A new offer
To resolve this issue, you need to sign in to your bank or FI's website and either dismiss or act on all notifications. If you don't see your notifications, you may need to disable your pop-up blocker.
Once all messages are acknowledged, you can go back to QuickBooks and run a manual update.
From the left menu, select Banking.
On the Banking page, select Update.
If prompted, enter your Multi-Factor Authentication (MFA) credentials and select Continue update.
