I filed the way TurboTax filled out NYC-208 for me (showing interest for the whole property) for 1996 and got a note from NY disallowing the deduction.  This year, TurboTax did the same thing so I got the instructions for the form and, the way I read it, I should only show 50% of the tax.  Wanted to check with others before sending in my tax return.  It would seem that TurboTax needs a correction (especially since it already knows this is a 2 family house and I live in one apartment).  How can we get TurboTax to chime in here?

Just to clarify - 1996 is the total amount? Was this for last year? What about 2015 & 2014?

When I used TurboTax to complete me taxes for tax year 1996, it put the entire amount of real estate tax for my 2 family house on NYC-208 and it was rejected by New York.  Now, when completing my return for tax year 1997, TurboTax did the same thing which is what let me to ask

OK you mean 2016 & 2017 then. I'm going to use what I use for my federal expenses - 50% for the amount of the property that I occupy.
