Refunds from FAFSA (Pell Grant and Texas Grant)

Hello everybody,

I have never filed taxes before. I'm a full-time college student and I have never had a job before so that is basically why I have never filed taxes before. Fortunately, my fafsa has covered all my tuition since Fall 2019. Also, since Fall 2019 I have received some refunds from my FAFSA (Federal Pell Grant and Texas Grant). My question here is that if I need to file those refunds as income tax, and how do I do that?. I just had this question and it worries me a lot because I'm receiving refunds since Fall 2019.
