Did you e-file your son's return first——and now is your return that claims him as a dependent being rejected when you try to e-file?
You cannot e-file this year---at all, When you filed a tax return that said no one could claim your son \ as a dependent you put his SSN into the system and it will stay that way for many months even after you amend his return. No one else can e-file a tax return with his SSN on it, so now the only way you can file their your return that claims him is by mail. The IRS processes mailed returns a different way, so the duplicate use of the SSN will not stop the IRS from processing your mailed return. The problem is that it takes the IRS a lot longer to process mailed returns, so if you need your refund you will wait a lot longer for it.
When his return has been fully processed, you will have to amend it. When you amend you will go to My Info. Click his name and go through the screens to the question that asks if he can be claimed as someone else's dependent. You need to say YES. Do not amend yet. Wait for the IRS to process the return. You do not need to wait for your son's return to be amended. You can mail your return whenever it is ready. Waiting will not help you.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
