You do not say who the person is. And your post cut off mid-sentence. If you were trying to say that now the person cannot e-file--that's right. The person's SSN was used on your original return and will not be taken out of the system as such for a very long time. Your amended return is probably sitting in a mail bin at the IRS. They are not even opening the mail, and will not be processing amended returns for quite some time. The person you claimed will have to print, sign and mail their own return; they will not be able to e-file this year.
