Hi there, @kristinafarrey.
Thanks for bringing this to my attention. I'm here to help share some troubleshooting steps so you can connect your credit card to QuickBooks Online.
Did you receive any error message while trying to connect your credit card accounts in QuickBooks Online? If so, you can check out this article about fixing online banking errors in QuickBooks Online.
On the other hand, we can also try running a manual update to refresh the connection between QuickBooks and your financial institution.
To do that:
For more details about this process, you may refer to this article: What to do if bank transactions won’t download.
If you’re still unable to connect your credit card account, you can use the WebConnect feature to manually download your bank data into the program.
If the issue persists after trying these steps, I'd suggest reaching out to our Customer Care Team. They have the necessary tools to check on your account and help verify what's causing the issue.
This should help you connect your credit card accounts into QuickBooks Online.
Please let me know how it goes by leaving a reply below. I'll be around if you have any other questions with bank connections. Have a great day.
