Hal,
My son lived with me from January thru mid July in 2019 while he was finishing his senior year in HS. He joined the military in mid July.. I did not know until my federal and state returns were rejected that he had his mom ( my ex) file his tax return. Now there are obviously (2) tax returns with his SS number... it would be cumbersome to have his return amended.. any other options aside from just not claiming him?
