Thank you!  I was getting hung up on the refund coming from the vendor and was selecting that vendor in the Received From column.

I could also use a vendor credit, which I tried.  Using this way, I was getting hung up on the visual in the Vendor >> Transaction List.  When you use a vendor credit, then match the deposit to the credit by classifying it to Accounts Payable, then using a bill/expense/check to zero out the outstanding amount, total on the transaction list page shows that the amount is subtracted twice.  However, when I check the affect of the transaction on the Income Statement, the expense account is correct and Net Income is correct.  It's just a visual oddity on the Vendor Transaction List page.
