Stimulus Check Eligibility ?

I'm 20 years old and a part-time student. All year I've paid out of pocket for community college without a source of income (lot's of saving). I filed my taxes for the first time for 2020 and got a pretty hefty refund for paying so much for school. 

Because I filed on March 11, my refund was processing through the dates of the first two stimulus waves (March 17th and march 26th). Is there any chance that I still can get it? Am I even eligible for it? No one has claimed me as a dependent, like I said before my return has already been received. Every time I check the "Get My Payment" I see the words "Payment Status Not Available".
