I am late filing my 2016, 2017 and 2018 Fed and state taxes. I was self employed for 2016 & 2017, not for 2018 (& 2019) and also moved in March 2018, CA to UT.

You can only buy the download for prior years.  You have to buy a separate program for each year.  They only sell the last 3 years.  You need a full Windows or Mac computer to install it on.  You can buy any version.  All the Desktop programs have the same forms.  You just get more help and guidance in the higher versions.

You have to print and mail prior year returns.  When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return.  Don’t forget state.
