You can look at your credit card bill. It will be displayed after it is credited. If it has been returned recently, most of it will appear in "Unpaid Bills". For repayment transactions, there will be a "-" prompt before the amount. There will also be a transaction description, you can pay attention to it.

In addition, taking the CCB credit card I use as an example, there will be SMS notifications for repayment transactions, you can also check it.
