It was a claim of Partial Disallowance.  We did meet all the timelines but IRS kept extending theirs till over a year.  We did send in the paystubs that matched the W-2.

The SS department did not have this W-2 recorded and the Payer said they corrected that by filing.  We haven't checked to see if done.

Did get a letter from TAS stating successfully resolved and closed the case.  It said IRS will correspond with details.  That has not happened.
