How do I file my 2017 income tax

To complete and file a 2017 tax return using TurboTax you would 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.

Tax returns for years prior to 2020 must be completed using a CD/downloaded version of TurboTax.  Only the current year (2020) return can be filed using TurboTax Online.

The 2017 version of TurboTax is available for purchase and download to your computer.  After creating the return it must be printed and mailed for processing. 

Here is a link to get started with the past year's returns with TurboTax:  TurboTax 2017 Products

If you expect to receive a refund for your 2017 tax return, it must be filed by May 17, 2021.
