Can I calculate my mrd on a retirement account without knowing the total?

I have a government retirement that has no way of finding balance.

Say all of it is the RMD.  When you turn 72  it will ask you if it is the RMD.  Say yes.  Anything your pension pays you is considered to be the  RMD.  Traditional pensions automatically fulfill the rules of an RMD. So for the RMD question put in the same amount as box 1.

One reason it might ask is to determine if your 1099R is eligible to roll over to another qualified retirement account.  Which a RMD is not eligible.
