My adult son was unemployed last year and living at home. According to TurboTax, he was eligible, so we filed a federal return, which has been accepted, that listed him as a dependent. He decided to file his own return to receive the stimulus checks but didn't realize we already had him listed, so his return was rejected. We earned too much to receive any stimulus checks. Are we allowed to file an amended return, removing him as a dependent? If so, what reason should we give in the box marked "Explanation of Changes"? How soon will the change be registered at the federal level so that he can refile his own return?
