Are you asking how to reinstall 2024 or get the 2024 tax returns to transfer into 2025 and to amend 2024?
Since you now have to log into an Intuit Account when you first install it, all your downloads and licenses are listed there (even if you bought it from somewhere else) so if you need to install it again or install on another computer, even on the other operating system (Windows, Mac) you can download it again. And the download will have all the updates.

But if you can't find the tax return files ending in .tax2024 you can't transfer or amend 2024. You would have to redo them from scratch.
