Click his name in My Info. Go through the screens to the question that asks if he can be claimed as someone else's dependent. The answer needs to be YES, and YES to the next one that asks if someone will claim him.
Your own return that claims your son will have to be filed by mail. When he said he could not be claimed, he put his SSN into the system for the rest of the year. You are blocked from e-filing with his SSN on your own return, so you will have to file your own Form 1040 by mail to claim him. Print, sign and date your own return in ink, and send it by mail. You do not have to wait for his amended return to be processed--waiting will not help.
