This response is INCORRECT.
You can download all your previously licensed downloaded Desktop software. As another reply above said, you need to log into your account. However, the link that other response provided (also available by Googling) does not seem to be working.
I just found the following link to work:
https://accounts.intuit.com/app/account-manager/security
You will see a list of all your previous desktop licenses. It doesn't look like there's a downloadable link, but click on that big mass of information, and you'll find a right-facing arrow show up. Follow that, and you'll find all your previous purchases (of desktop software) listed, with download links for each. I just tested that I was able to download at least as far back as 2017 (doing so in July 2025).
Cheers,
A
