Amend older return: use 2024 TT or TT from prior year.

I need to amend my 2023 return.  It's in and archive folder on my pc...PDFs and what I believe is the TT formatted file.

 

I can not open the file with the 2024 software. I tried starting 2024 TT and browsing to my archive folder etc. It won't open.  I tried double clicking the TT file from windows explorer...still prompts me what software to use?  Must I reinstalled the 2023 software from CD to open? How does one access a prior year return to amend
