Form 1099-R from Broker, what amount should be entered Box 16 - State Distribution

Anything in box 14? If not then leave boxes 14, 15 & 16 blank, no spaces. If you have withholding in box 14 then enter the same amount as in box 2a. If box 2a is blank use the amount from box 1.

Yes pension is RMD.  It's whatever they send you. Say all of it is the RMD. If you have a RMD requirement it will ask you if it is the RMD. Say yes and enter the amount as the RMD amount. 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. So just enter the same amount in box 1 for the RMD for each 1099R.
