Treatment of Gratiuty received from employer after layoff

Hi,

I lost  my job during the peak of COVID crisis in Dec 2020. My employer paid me Gratuity amount in August 2021. Now when filing for taxes for FY 2021-22, I am not sure if the gratuity amount I received is tax exempted. I was jobless for months of Dec 2020, Jan 2021 and part of Feb 2021. Not sure if I can apply for deductions under section 10(10). The amount I received is less than 3 lakhs. Interestingly the employer has not deducted TDS on the Gratuity amount . It would really help if someone can guide me on this. Thanks in advance !!
