The last couple of years you have to log into an Intuit Account when you install even from the CD, so 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). And the download will always be up to date with all the updates.
If you have a License Code 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.
