Let me provide a little more info ....

There were a number of credit card entries that were entered directly into Deposits, never having been first entered as a receipts via the "Receive Payments" process in the Customer Center. I wanted to identify all of these and remove them as they were duplicates of dollar amounts entered via entries from a POS system. So yes, I understand how the system works. 

I printed a Deposit Detail report for the period where most of the entries occurred, and filtered Transaction Type to only show Deposits, and then filtered Payment Method to show if payment was made by credit card. It actually showed payments made by Cash, Check Money Order , and ACH. I then tried to filter so it only showed the credit cards. This resulted in the blank screen. 

I was eventually able to achieve my goal by just manually identifying the credit card entries and ignoring the other payment methods. We do have payments that are received directly via deposits and not "Payments Received" because we receive funding to reimburse allowable expenses, so there are a significant number of entries that bypass the Undeposited Funds type account.

But I do thank you for the links you provided. Perhaps some of them will help in this or other areas.
