Self employed, Covid, W-2, Previous yr deductions

I was self employed before the pandemic and was on unemployed cause of covid last year. My question is, if I am now receiving a W-2, am I still able to deducted expenses related to my rideshare costs from last year like - upkeep for the vehicle used for business if I didn't work last yr i.e registration, insurence, phone bill etc? I am re-register on the platforms and can start working again as a contractor.
