NY AGI computed by Turbotax differs from AGI calculated by NY dept of taxation

Based on the information entered on my federal return via Turbotax, the NY ADJUSTED GROSS INCOME is 13,500 more than the NY AGI computed by NYS. The various other state deductions, state taxable income, state income tax and total overpayment computed by NYS are less than these amounts calculated by Turbotax. Why?
