You can download previous versions of TurboTax CD/Download using one of the links on this page: https://turbotax.community.intuit.ca/questions/1364511-where-can-i-download-the-cd-download-edition-...

Went to link.

Would not download previous years.

I have installation code, but was never asked for it.

Would not download

I went to the link and tired to download standard version for 2016 and 2017 but no response when I clicked on the link. To test links I clicked on the Business Incorporated link and it did download that file. It appears the link to 2016 ans 2017 standard version is NOT working???
