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.
Access your downloads here
https://shop.turbotax.intuit.com/commerce/account/secure/login.jsp?pagecontext=download
OR you should be able to download 2021-2023 here on the prior program page. Click on the little blue “access it here” link at the end of the top paragraph. It should take you to log into your account.
