Answer:
Assuming that the Fed handled one of the items, you can submit a "PAID" adjustment claim with the Fed to obtain a refund. It can be used on an electronic payment (image) or paper payment.
If you received the items from a clearing house other than the Fed the clearing house may also have a warranty provision that will allow you to push the loss to the other bank.
