Addendum:
It's recommended to prepare 2019 first (using the 2019 desktop software as explained above.) Then we can tell you how to transfer the 2019 data file into your 2020 return when you begin the 2020 return. That's especially important if you have carryover items from 2019 that have to be accounted for in 2020 such as depreciation, capital gains/losses, etc.
Also, if you efile the 2020 return, during efiling it will ask you to verify the 2019 AGI. Since you did not file a timely 2019 return last year, you would enter a 2019 AGI of 0 (zero) when efiling the 2020 return.
