Include only actual military retirement income in the box titled "Military retirement income included in federal income".
Do not include any of your civil service retirement income in that box, not even the amount attributable to military time. TurboTax (TT) will do that calculation for the amount of civil service pension excludable and then add it to the amount of actual military retirement (if any).
It is working correctly on my program (desktop [download] Deluxe).
