Very disappointing that TurboTax does not support the calculation for a Box entry on a W-2! Even more disappointed that Turbotax made me file by mail both for Federal and State because of this. The point about further adjustments being required seems like a weak excuse - I don't see what further adjustments could even exist in my case, this was a very straightforward case. Turbotax should have immediately flagged Box 12 Code Z when the W-2 was imported and provided a warning that TurboTax would deny e-file and force File by Mail. First bad TurboTax experience ever.
