I actually got three W-2's last year from two different employers.
Employer 1 issued me one W-2 for the first half of the year.
Employer 2 employed me for the second half of the year, but due to a change in their ownership in third quarter, I was given two separate W-2s (one for old ownership and one for new ownership) with the same EIN. The total SS withholding on all three adds up to the Turbotax included amount.
Could that be the issue?
