Retirement under disability question

Ok sorry if I'm sounding stupid here. Trying to understand this all.  My husband had to retire under disability at age 59 in June 2019, 2 weeks shy of his 60th birthday . When Turbo ask "Were you under your minimum retirement age when you received the distribution?", what does this mean exactly? How do I find out? Am I answering Yes or No?  Also, since he was then retired under disability, my husband received a monthly check for his retirement and also a check from SS for disability (i believe).   Then Turbo ask "Any periodic payments -- did my husband  receive payments from this retirement account on a regular basis, such as monthly, quarterly, annually".  I'm going to assume I should answer "Yes" since he was receiving monthly deposits correct? Can't ask my husband because he passed away last year :(  I now continue receiving his retirement for few more years, but not his SS until I reach age 60 for survivor death benefits, but that's different topic.  Confused as hell!
