Welcome to this thread, DDCabinets.

I appreciate you for following the solution shared by my peer and sharing the result. This information will guide us on how to resolve your concern.

Since the deposit is recorded after receiving the payment, that’s why you’re unable to see it in the Related Transactions section. Let’s delete the deposit first in your register and then the payment. I’m here to help ensure you can do these tasks smoothly.

1. Open the company file and go to the Lists menu at the top bar and select Chart of Accounts.
2. Select the account you recorded the entry and open it.
3. Look for the deposit you wish to remove and right click your mouse beside it and choose Delete Deposit.
4. Click OK in the Delete Transaction window.

Next, open the customer’s Transactions List to delete the payment. Here’s how:

1. Tap the Customers menu at the top bar and choose the Customer Center.
2. From the list, select the customer and go to the Transactions tab.
3. Find the payment and double-click on it to view more details.
4. This will take you to the Customer Payment screen.
5. Click the Delete button and OK to confirm the action.
