You cannot E-file an Amended tax return.
Wait until the end of the month of Feb, in case something else "shows up" that has to be included...then you have to print it out, (he has to sign/date.)..etc, and take it to the Post office and mail in the amended paperwork. Amended tax returns can take 1-3 months to be processed, since they are manually entered.
