You Really-really need to call Customer Support, and let them work thru the details of that problem.....the exact values need to be tested, and a ticket written to get it fixed. But that can't be done without the gory details that are on your W-2 form so they can SEE under exactly what conditions the problem occurs. This would help not only you, but thousands of others too:

Make sure you go back and EDIT that W-2 to make absolutely sure the $$ amounts are correct. People commonly slip up on decimal point placement, or hit a comma instead of the decimal...and that screws up the number without them noticing.
