No...You cannot. The Online Free edition (or any of the Online editions) can only be used to for filing a 2018 tax return. No other years. and when it closes down in October, it will open up later to only prepare and file 2019 taxes...nothing else.
For prior years, like 2016 and 2017, you will need a full MAC or Windows computer, and you will need to purchase, download, and install the desktop software for each year needed. And prior years can only be printed and mail-filed by you at the Post Office:

Of course...if simple enough, you could go to the IRS website and download the PDF forms and instructions for each year and prepare them manually.....but that's up to you.
