Banking

Hi there, @trailways.

I appreciate you sharing the steps you’ve taken to connect your bank with QuickBooks Online. Let me share some information about the error you met. 

QuickBooks downloads and categorizes bank and credit card transactions for you when you link an account. It inputs the details for you so you don't have to manually enter transactions. Here's what you need to do to get QuickBooks to download transactions again.

Keep your bank information up to date on their website, such as your account number, username, and password. Then, in QuickBooks, update that information as well.

Here’s how:
1.On the left navigation bar, select Banking
2.Go to Banking tab
3.The bank account tile should be selected. Then click on the Edit icon.

4.Tick Edit sign-in info.
5.Update your info as needed.

Furthermore, you can also check this article for the downloaded transaction in QuickBooks Online.

Thank you for your patience and understanding. Feel free to reach out to me if you need anything else. I’m always here to help.
