Problems with feeding in barclaycard to quickbooks

Welcome to the Community, @angelaj-bartlett.

Let's manually update your Barclaycard account to download your bank transactions successfully in QuickBooks.

1. From the left menu, click Banking.
2. On the Banking page, select Update.
3. If prompted, enter your Multi-Factor Authentication (MFA) credentials and select Continue update.

I've got you an article for more details: How to Manually Update an Account.
