Thanks for all for the feedback! 

Just to update, the tax preparer of the 2023 1120-S finally got back to me and confirmed, among other things, that he filed an extension for the 2024 1120-S so proceeded with filing the 1120-S. The reporting directly on 1040 was a viable option had I not gotten copies of the 2023 1120-S return.

SO, I've completed the 1120-S for 2024 and will move forward preparing for 2025-2027 as well. The pass thru will also allow for the proceeds to be exempt from NIIT given his material participation.

FYI - not an LLC; entity is a PC in Virginia setup as an SCorp + turns out the basis was overstated due to 2024 distributions taken.

Thanks again!
