Is it a pension? If it's not an IRA or 401k plan then probably all of it is considered to be the RMD. Did you tell them how much you wanted to take out? Or are you getting regular payments like monthly?
For pensions, If you are 72 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.
