Fastest way... 1. You have to delete your son's information from your original return. 2. Re e-file, your tax return. After you get the refund without your son as a dependent. THEN 3. You have two choices. Amend your son's tax return online first. Wait until his return is accepted then amend yours online.
OTHER choice paper file both amended tax returns and send your son's return and yours together in the same envelope. Good luck
