Even if you find a 2017 TurboTax download or CD you will not be able to install it or run it. Also, the download or CD will not be fully updated, but you would not be able to get updates or state programs. TurboTax only supports the current year, which is now 2025, and three previous years, 2024, 2023, and 2022.
Some other tax software companies might still have 2017 software available, but that's pretty old. You can download federal forms and instructions for 2017 from Prior year forms and instructions on the IRS website.
