Hi there, @jwest2!
Ideally, you'll have to create each credit card account for every expense you made since they're separate transactions and separate accounts. But if you track your expenses as one, you'll only need to create only one credit card account. You can read through this article to learn more: Add an account to your chart of accounts in QuickBooks Online.
In addition, I'd recommend contacting your account for additional assistance especially with how you can handle your credit card accounts
Lastly, here's a few articles you can read for ideas about how you can manage your account and transactions: Reports and Accounting for QuickBooks Online.
If you have any other questions, you can leave them in the comments. I'll be here to lend a hand.
