refund and credit memo

Welcome to the Community, @xiao8325. I'll assist you today in handling your given situation about refunds and credit memos in QuickBooks Online.

Since you've issued a refund for your customer via bank, I suggest deleting the Credit Memo that shows as Unapplied. To delete it, pull up the Transaction List by Customer report, and customize it to show the credit memos only. I'll guide you on how:

1. Go to Reports.
2. In the search bar, type Transaction List by Customer.
3. Click Customize. Select the arrow next to Filter.
4. Choose the Transaction Type drop-down arrow, then choose Credit Memo.
5. Click Run report.
6. Locate the credit memo that needs to be deleted.

For additional resources, I've added an article that provides detailed information on handling credits and turning on the auto-apply feature: Create and apply credit memos or delayed credits in QuickBooks Online.

Hi Thank you so much for the fast response. So What am I going to deal with the refund transaction showed on my bank? If I do the refund receipt, it will do another refund to the customer. 

Thanks.
