Turbo tax not subtracting out US Treasury Interest on New York State forms

The interest income on U.S. government bonds is subtracted on Line 28 of your IT-201. Although it may look like it is being included in your taxable income, it is also being deducted on the later part of the form. 

my line 28 was prepopulated. do you know where/how turbotax prepopulated the line? where did it get that info from? tx

When you entered your 1099- INT, you told the program you had US interest in box 3. You may have also selected to adjust the amounts for other boxes while in the federal section.
