You said, "I was not and I am not working.." " I have been filing taxes.."

What a conflict statement.

IF you have NO income, however, you aren't obligated to file tax.

Or you meant to say you have W2s for the year 2019, and you're unemployed the whole year of 2020.

Clear this out first what you meant to say, and by the way, and please mention, where do you live?

PLEASE NOTE: TPS holder can file for unemployment and it is NOT under public charge regulations.
