Ooops - I was using EIC by mistake; ran out of room to ask the original question and used incorrect acronym. This has to do with Education Tax Credits. I submitted the 1098-T. In reply IRS asked for Proof of Payment. When I asked what would suffice they did not reply. So I am left guessing. Cancelled Check? A notarized statement from me indicating that I paid the amount. Hoping the latter as I closed the account from which I wrote the check and no longer have any accounts with that bank.
