Minimum Required Distribution and Annuity plan cost

I have read that if I have been receiving monthly pension payments that my total annual amount is my MRD. I am 73 years old and have been receiving these payments since 2013. Yet when I called my pension administrator to verify, they said that there is no MRD. So I entered 0, but am not sure if that's correct.

Also, I'm stuck on the question on the Annuity Information section where it asks for my plan cost. I have read that the amount in box 9b is the plan cost, although it's blank on my 1099-R form. So does that mean it's 0?

Thanks for any help you can provide.
