Neither I nor the software are ready for prime time yet, but I am continuing to check it out. When I Transfer a 2020 F1040 (which had 8915E) into 2021, F8915A-T appears in the Forms in Use listing, and 0 appears in green in line 1.

 F8915-E appears in the LOAF(List Of All Forms) but has nothing on it.

For later exploration: does the one-third amount go on 1099-R, code 2 for no penalty?

(FYI: F8915-E appears when looking at the LOAF, and when using F6, but it does NOT appear when searching using the green "Where do I enter?" button.
