Should I file a tax return? I worked a few days in 2020 and had re-signed from my previous job and have not worked for the whole year and not doing unemployment

I have not had a job since last year 2020 and cannot understand the online form, under income I still have my company that I worked for but don't know if I need to change something or just press continue and no I have not gotten my W-2 form from last years working and have not had a job ever since. Yes I did file a 2019 tax return last year. Yes I still receive the stimulus checks.
