If someone used your SSN on a tax return, the reason your own return was rejected is that the other return was accepted. The IRS does not "reject" a return after acceptance, so, no, that other return will not be rejected now. But since the IRS will see two returns in the system using the same SSN, the IRS will sort out the duplicate use of the SSN's. Hopefully your return will be accepted with the IP PIN; but do not be surprised by a letter from the IRS someday when they are sorting out why your SSN was used twice.
If your e-file using the IP PIN is also rejected, you will have to file by mail.
