Hello lwilkerson!
Thank you for reaching out to us again. I can help you with the banking.
Capital One is one of the hundreds of financial institutions that QuickBooks Online supports. This means you can connect and download the transactions.
Upon checking, all investigations mentioned in this thread are already resolved. You can follow the steps in this article on how to link the bank account: Connect bank and credit card accounts to QuickBooks Online. At the bottom part of this article, you'll see a link on how to fix banking errors, if you'll encounter one.
Also, here's a guide on what to do with the downloaded transactions: Categorize and match online bank transactions in QuickBooks Online.
I'll be here if you need anything else. Have a great day!
