Yes, KY has a subtraction for all pension income up to $31,110. This is automatic and once you complete your KY state interview you will see the subtraction on the last screen. If your pension 1099R was more than $31,110 then you will be asked a series of questions in the KY "Income" section of the state interview to determine an additional subtraction percentage of your federal pension. Since your pension is federal government you may be eligible for an additional subtraction amount based on your years of service.
