@BrendaMartin99 Yes you can file 2020 until Oct. 15, 2021. Are you stuck somewhere? Have you started 2020?
Click on Add a State to let you back into your return.
From Tax Home (the first screen you see after you sign in), scroll down to Your tax returns & documents. You may have to select Show to open the drop down.
Select 2020, and then select Add a State (you're not actually adding a state, this is just the workaround).
