I am having this problem too. As far as I can tell form IT-398 is being erroneously generated. I have a 27.5 year straight-line depreciation property. This form appears to be for accelerated depreciation allowed by the Fed but not by the State of NY. My property does not qualify for this type of depreciation (section 168) and I have no idea why TurboTax generates the form, let alone where the numbers came from. I could not edited the values or delete the form. Also, I was unable to find in the place in the work sheets to tell TurboTax to ignore the asset for state tax purpose referenced by a previous post.
