23000 was withdrawn from the account and the form asks if any of this was the MDA and how much was the MDA

[JohnB5677]

Did you mean RMD (Required Minimum Distribution)?  When you reach age 72,* you're required to withdraw a certain amount of money from your retirement accounts each year. That amount is a RMD.

If you were not over 70 1/2 at the end of 2019, none of it was an RMD.
