The RMD question is asking how much of the distribution was RMD is used only to determine the amount that is eligible for rollover, not for determining any penalty; the question is actually asking how much of the distribution is not eligible for rollover. In the case of a non-spouse beneficiary, it is all ineligible for rollover, all RMD. If you didn't roll over any of this distribution, it doesn't matter how you answer this question.
