If you choose to use TurboTax to complete a 2017 tax return then you will need to purchase, download and install on a personal computer one of the 2017 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/
A 2017 tax return can only be printed and mailed, it cannot be e-filed.
I also paid for the 2017 edition. I downloaded the file. I click on the .exe file and it doesn't do anything. The desktop pointer icon just sits there and spins indefinitely. I waited 10 mins for it to work and nothing happened. The only way to get it to stop was to restart my computer. I went back and re-downloaded it again. same results.
