If you have a pension, you simply check yes that it''s all an RMD. The fact that a pension, or even an IRA distribution, is an RMD does not change the taxability of it, it simply avoids a penalty for not taking an RMD.
All pension plans are required to pay RMDs, lust like an IRA. The only difference is that, if you take pension distributions according to the plan requirements in retirement, the tax law defines that as meeting the RMD requirements.
