Hi, @Jc-sbwa. I appreciate you joining the thread. 

Let me help you identify which of your customers you can charge the Credit Card (CC) fees to in QuickBooks Online (QBO). 

Since you're using QuickBooks Payments, you can consider directly checking your Merchant Service account to find the fees associated with your customer transactions. You can follow these steps:

1. Sign in to the Merchant Service Center.
2. From the Activity & Reports menu, select Fees.
3. Select the Dates ▼ drop-down menu to change the date needed. You can filter any six-month period in the last 12 months.

Alternatively, you can consider running the Transaction List by Customer to view all CC payments from your customers. Here's how:

1. Go to Reports. 
2. In the search field, type Transaction List by Customer and select the report.
3. If applicable, click Switch to classic view. 
4. Select Customize.
5. On the Customize report window, edit the Report period.
6. Once done, click the Filter dropdown.
7. Tick the Transaction type, then select Credit Card Payment in the drop-down menu. 
8. Hit Run report.

For future reference, let me add this article to check when QuickBooks deposits customer payments into your bank account: Find out when QuickBooks Payments deposits customer payments.
