When I filed my clients' returns, it rejected it due to a duplicate dependent social security number.  I notified the client and asked if their oldest son filed a return.  He did and must have claimed himself (doesn't remember that it asked him the question about parents claiming him).  He is only 17 years old.  I amended his return with him not claiming himself and he gets small refunds (he entered taxes withheld wrong on federal and state).  The son's federal amended return was accepted on 3/24.  Can't efile Ohio because it is not one of the states you can efile.   Keep trying to efile his parents returns again and they reject them.  Will I be able to efile the returns this year or do I need to prepare them for them to send them in?

Thank you for your help.
