I have read the thread and I'm still confused how to do this. In the bank Deposit Screen, at the top is "Deposit To".  Would that be the bank that I wrote the check out of (ex:chase) or an income account you mentioned such as "sales income"? 

Below that is "Received from": ?? and "From Account":?? The explanation here isn't specifying what is going in each location. Is the Customer going in Received From?  Is Sales Income going in "From account"? 

The old refund check is still showing up to reconcile in the bank account and I want to clear it out of there.

The Customer's open balance report is showing the overpayment amount (negative) on one line and the refund check amount (positive) on a 2nd line, making them at zero as it should.  I do not want to void the check and reflect that we still owe it to the customer since it was errors on the customers part at the time 2 years ago and been resolved with them but these transactions are still here. 

Please include the details to fix.  Thank you.
