Hello there, @gloriadeb204.

In QuickBooks, the Record Bounced Check feature only applies to the Check payment. It's possible the icon is grayed out if the payment method is not a Check. 

Let's make sure that the check is selected on the payment method correctly. Let me guide you how.

1. Go to Click the Customers, then select Customer Center.
2. Select the Transactions tab. 
3. On the left pane, select Received Payments.
4. Find and double-click the payment you want to record as NSF.
5. On the Receive Payments window, select CHECK. 
6. Click Save & Close. 
7. Select Yes to confirm. 

Once done, you can now record the bounced check by following the detailed steps in this article: Handle Non-Sufficient Funds (NSF) or bounced check from customers.

Let me know if you have other questions by dropping a comment below. I'll be sure to get back to you.
