OK, thanks.
It was from my dad‘s 401k account from his former employer.
When we all (siblings too) received the money, we were told it was an inherited IRA, and that we had to take the required minimum distribution since he had not taken it yet for the year that he died.
I could be wrong though, what do I know. Like I say, if I check the box for other it lets me go through fine.🤷
