According to the IRS, this return should be e-filed, even though there is a discrepancy in the use of the ITIN and an unrelated SSN.
The IRS would rather have the return filed this way than for the return to not be filed at all.
To e-file this return
Enter the client's ITIN on the Main Information Sheet. The program sends this ITIN to the W-2.
Override the SSN field on the W-2 with the SSN the taxpayer actually used to claim wages for that job, so it matches the paper W-2 that the IRS previously received.
Create and transmit the e-file for this return.
The return will not be rejected by the IRS for the ITIN and SSN mismatch.
