If you used TurboTax Online last year, sign in to TurboTax Online for the tax year 2017 here: https://ww1.2017.turbotaxonline.intuit.ca/.  If you used TurboTax CD/Download and you saved it on your computer you can simply go to the Start button on the bottom left of your screen and click on Start and you will see a small search bar - type in .tt17 and you will find it there.  If you did not save it, unfortunately, there is not a way to access it.

I did that and still can't access the pdf - only portions that appear on screen, like summaries of income, credits etc. Is there a pdf form from 2017 Turbo tax online that I can access and print???
