It's not a data corruption problem or a printing problem!! I am having this same issue right now. It is a software issue in Quickbooks. Hey Quickbooks....Let your support/engineers know!! Or add it to your instructions in the W2c that you must enter the amount, if unchanged, in the SIT box for it to be correctly added to the form. Quickbooks just tripled our monthly "usage" cost for the Payroll service yet they can't even correct this issue still 2 years from the original post!! Oh and that is on top of the $400+ a year we also have to pay for the payroll service. It is ridiculous that I have to spend an hour trying to figure out what the problem is!
