I can help you with showing this invoice as paid and deposited, @victorgarciajr95.

You can update that deposit and change it the account to Accounts Receivable. Then, link this deposit to the outstanding invoice. 

First, you must edit the deposit:

1. Go to Customers tab and select the customer name.
2. In the Transaction List tab, click on the Filter button.
3. Choose All plus deposits and click Apply.
4. Select the deposit transaction. 
5. In the Account column, select Accounts Receivable. 
6. Click on Save and close.

To link the deposit to the invoice:

1. From the customer's profile, select the invoice.
2. Click on Receive payment.
3. In the Credits section, check the box for the deposit. 
4. Click on Save and close.
