When a client is a part year NY resident, but have itemized their deductions on the federal due to mortgage interest and real estate taxes realized in FL, are they entitled to take those deductions on the part year NY return?  If not, I can force the standard deduction, but on the NY IT 203 it is giving me the full standard deduction, whereas when I do the IT360.1 it is prorating the standard deduction.  I am not seeing anywhere to prorate the standard deduction on the NYS part of the return.  Help!
