It looks to me like a design flaw that has been enhanced by a bug. No matter what number I add to either the Car Registration Fees line or the Personal Property Taxes line, it ONLY deducts from my State tax. I even changed my state to South Carolina, and the software did the same. Testing against TT2016, this is NOT what happened... both fed and state figures moved. And yes, I'm well under the phase-out limits for deductibility. Not sure how to deal with this now... manually prep a Schedule A? Ideas?
