Hello and welcome to the QuickBooks Community, giacomo-tonico-t!
We'll be happy to share some guidance on recording credit card repayments in QuickBooks Online.
There are a number of ways to do this, however, the main way is to use the Pay down credit card feature:
1. Select + New.
2. Under Other, select Pay down credit card.
3. Select the credit card you made the payment to.
4. Enter the payment amount.
5. Enter the date of the payment.
6. Select the bank account you used to make the payment.
7. If you made a payment with a cheque, select I made a payment with a cheque. In the Cheque no. field, enter the cheque number, or if you paid electronically, enter the EFT number.
8. If you want to add notes or file attachments, select Memo and attachments and follow the onscreen instructions.
9. Select Save and Close.
