Claiming a married child who filed MFS
Clients' MFJ return originally rejected because their son, who could be considered their dependent for much of the year, allegedly claimed himself. I got a copy of his return, and he did not claim himself but instead checked the box that said "someone can claim you as a dependent." Son got married in 2019 but filed MFS for that year. So I went ahead and filed without claiming son.
I know that his parents could not claim their son if he filed MFJ, but he didn't. What am I missing? I'd like to amend my clients' return if possible.
