Required minimum distribution: I don't know what the heck they are talking about.

TurboTax will start asking that once you reach age 70.5 (or perhaps 72 now).

For a standard pension sent monthly...it's still an RMD, and all of it is an RMD.....you just have no control over it.  The issuer is responsible for ensuring it meets the proper IRS guidelines.  Being an RMD, it is not eligible for a rollover to another retirement account.   Whereas, 401k, IRA, TSP distributions, just for 2020, are not RMDs even if they normally would have been required.....and these can be rolled back..... where normally that would not be allowed.

RMD stands for required minimum distribution. It's the minimum amount of money you're required to take out of your retirement plan once you turn 72.

RMD rules apply to all employer-sponsored retirement plans, such as pensions, profit-sharing, 401(k), 403(b), and 457(b) plans, as well as Traditional IRAs and IRA-based plans, such as SEPs, SARSEPs, and SIMPLE IRAs. However, RMDs aren't required for Roth IRAs while the owner is still alive.

RMDs were waived for 2020. If the Required Minimum Distribution does not apply to you then select none/ you were not required to take a RMD.
