@jenkel51101 The amended return will not clear the issue with the IRS rejecting your tax return. Since the IRS has already received a tax return with his Social Security number, that is coded in their database. The IRS database will not be changed by his amended return for this. You will have to print and mail your tax return and claim him as your dependent. The IRS will pay the refund, if any, based on his being a dependent.
