I refunded a customers credit card but the transaction shows up under not deposited. How do I remove this since it never was deposited into my bank account?

Resolving your issue is my top priority, Maria1114. In order to assist you effectively, I'll need to ask for additional details about the refund transaction that shows not deposited in QuickBooks Online. Providing me with more information about the specifics of your concern will enable me to understand the situation better and offer a suitable solution without delay.
 
May I know how did you record your refund for your customer's credit card? Any screenshot of the not-deposited transaction will also be a great help.

I'll look forward to your response. Thank you!
