After you file

I just re-read your question--- it sounds like you worked for part of the year--so that suggests you will receive a W- 2 from your employer for the wages earned before your injury.  So you will be able to enter that W-2 on a 2020 return.    Depending on the amount of tax withheld and the other variables like your filing status, dependents, credits you are eligible for, etc. you could receive a tax refund.
