After you file

So ... if you did not also include the education credit form  8863 the data input operator will simply ignore the unneeded/unused form(especially since it should NOT have been mailed in at all).   So now you wait for the original return to be fully processed and the original refund is in hand.  Only then should you amend the return and you now have time to get another copy of the form if you don't have one ... most colleges make that form available online so check with them.
