Years ago, I had a 403b set up. I left that corporation over 25 years ago. I ultimately I made a withdrawal in 2024. Why can't I select private distribution in TT?

the other options, public pension or military pension do NOT apply. I would like to select Private of other distribution/none of above. This is a 403B qualified plan. Now TT says I am not allowed to list the 2 different distributions with my state: (Washngton Mutual) and (Inv Co of America) . I don't want to delete each entry.
