How long until an amended return is recognized by IRS
I filed my son's taxes for him and when I tried to file my own I received a rejection notice from the IRS. I discovered I had neglected to check the box on his return saying someone else could and will claim him. I did amend his taxes and the amended return was accepted. I tried filing mine again and I get an error saying I'm using a duplicate Social Security number, which is my sons. I thought since I amended his return I would then be able to file mine but that doesn't appear to be the case. What should I do?
