1099-R

The program is asking because even though this is not a 401K the money in the retirement account was not taxed.  The IRS requires on retirement accounts where the tax was not paid in the beginning that minimum distributions be made even when the account has been inheritied.

When a retirement plan account owner or IRA owner, who dies before January 1, 2020, dies before RMDs have begun, generally, the entire amount of the owner’s benefit must be distributed to the beneficiary who is an individual either (1) within 5 years of the owner’s death, or (2) over the life of the beneficiary starting no later than one year following the owner’s death. For defined contribution plan participants, or Individual Retirement Account owners, who die after December 31, 2019, (with a delayed effective date for certain collectively bargained plans), the SECURE Act requires the entire balance of the participant’s account be distributed within ten years.  There is an exception for a surviving spouse, a child who has not reached the age of majority, a disabled or chronically ill person or a person not more than ten years younger than the employee or IRA account owner. The new 10-year rule applies regardless of whether the participant dies before, on, or after, the required beginning date, now age 72. - IRS website.
