I filed my federal tax return several weeks ago and have already received my return. In that return, there was a dependent worksheet included for my 21-year old son. TurboTax determined he was not eligible to remain a dependent since he was no longer a full-time student. Net, he was NOT listed as a dependent on my return even though there was a worksheet included to determine such. Today, I filed my son's return with the selection that NOBODY could claim him as a dependent. His return was rejected because ANOTHER return had used his TIN. Net, I changed his return to someone could claim him and did claim him. This return was ALSO rejected. I don't know what to do.
