You don't have to worry about that anymore. Since you now have to log into an Intuit Account when you install it all your downloads and licenses are listed there (even if you bought it from somewhere else) so if you need to download to install it again or install on another computer, even on the other operating system (Windows, Mac).
I bought the download from Costco for 2023. Since you now have to log in to a Turbo Tax Account, the License Code and download are listed in my Turbo Tax account. Access your downloads here
