Retirement tax questions

I am in the identical situation as you described.   My Mom passed away end of 2023 but I was given an NR4 for the income generated until early 2024.  May I ask how you filed in the USA using TurboTax?  I have seen posts that say the income is Retirement Income and others that say make up a 1099.

 

The code for my NR4 is 06.  Appreciate anything you can share.
