report to show how much is charged to credit card per expense category

Welcome to the QuickBooks Community, amccl7.

I've got steps to ensure you can pull up a specific report that you need in QuickBooks Online.

I recommend running and customizing the Transaction Detail by Account report. This allows you to determine how much you've been paying per expense category on your cards vs your bank account, as well as the particular charges to a credit card.

Here's how:

1. Go to the Reports menu at the left panel.
2. Use the Find report by name search bar to search for Transaction Detail by Account. You can also browse the list.
3. Click the Customize button.
4. Choose the Change columns link and checkmark the Transaction type, Name, Vendor, and Account.
5. Go to the Filter drop-down arrow and checkmark the Transaction Type, Distribution Account, Account, Name, Vendor boxes, and other needed info you need.
6. Click the Run report button.

In case you need steps on how you can memorize a report that allows you to save it with its current customization setup, you can read this article: Memorize reports in QuickBooks Online.
