Hello Ben,
In addition to Lynda's answer, here's how you can view the deposit payment for the said invoice:
1. Open the affected invoice.
2. There are two tabs on the right-panel of the Create Invoices window.
3. Go to the Transaction tab.
4. Under RELATED TRANSACTIONS, it will show the deposit you use as the payment.
5. Click the deposit transaction. It will open the Make Deposits window.
6. Click Edit at the top menu, and select Delete Deposit (Ctrl + D).
7. Click OK to confirm the action.
After deleting the deposit, it will open the invoice again.
I'll be around if you need more assistance with this.
