Hello @gail315,

All transactions downloaded into your credit card account depends on the data shared successfully by your financial institution. You're on the right track in manually uploading them for keeping up a record in your account in QuickBooks.

Below are some instances which can be the reason why your credit card accounts won't update automatically:

• If there's a minor or major update in your bank or credit card information 
• An update on your bank or credit card's website
• Changes in your Online Banking Login credentials
• Bank or credit card outage and other scheduled maintenance

With this, I'd recommend contacting the Technical Support of your financial institution. From there, a specialist can help you map your credit card accounts accordingly so your transactions will be downloaded correctly.

For the steps in organizing your online transactions and keeping with the accuracy of your credit card account balance, consider reading this helpful article for reference: Categorize and match online bank transactions in QuickBooks Online.
