military retirement is paid out monthly automatically, without choice, this is not a typical pension plan, an RMD is not applicable yet turbo tax treats it as a typical retirement account.
Say all of it is the RMD. If you are 73 it will ask you if it is the RMD. Say yes. The pension doesn't need to calculate any RMD. Anything your pension pays you is considered to be the RMD. Traditional pensions automatically fulfill the rules of an RMD.
