Do I need to file my own taxes? I was a dependent and had excess scholarship funds

Hello. I'm currently a third-year college student. I have a combination of scholarship and pell grants to cover my expenses. I was claimed as dependent on my dad's taxes in 2019 and 2020. But I never submitted a 1098-T. My scholarship reimbursement was $5,500 for 2019 and $13,761 for 2020 (3 semesters). My first job was in 2020 and it was less than $1,500. Most of those funds are still in my bank account, I'm saving for my graduate school. Am I supposed to file for my own or add to my dad's, my scholarships for 2020 since it's over $12,500? Will IRS get those once I file for my own for 2021?

 

I was searching over the internet if I'm supposed to file in 2020 for my own but I read that my W2 should be at least 1200 or 1500. But now, I'm not sure of that. Thank you so much.

 

Also, I was told by our finaid office that I don't need to put those excess funds on my FAFSA app?
