We filed our taxes (Fed/Mich) and mistakenly claimed my daughter as a dependent though she doesn't qualify. I can't efile her return after amending mine. Involves 1098T.

She is 22, but her income was too high. A SARSEP disbursement meant she had a 1098T, which I like to apply to her filings. My amended returns were accepted 3/31. Do I need to have her manually file signed printouts of her returns to Federal and Michigan authorities?
