You do NOt need to file a tax return, per IRS rules, if that scholarship was your only income. It does not meet the $12,200 filing threshold*.
Colleges don't send out form 1040. If your's sent you one they also sent you an explanation of why they sent it. It sounds like they expect you to file a 2019 tax return to continue to be eligible for financial aid, so they thought they were being helpful with a blank form. You're gonna have to to get that straight with them, not, here, in this forum.
It also sounds like your insisting that you are not a dependent (when you almost certainly are) has to do with qualifying with financial aid. Again, you need to get that straight with the financial aid people.
That said, to report some of your scholarship, as income, enter your 1098-T, in Turbotax and follow the interview. Computers, generally, qualify as an educational expense**, enter at books. It sounds like you have 2000 to 3000 of income, which is not enough to have to pay any tax, but will allow you to file a tax return.
*The $12,200 filing threshold applies to earned income and scholarship income. If you have misc income, including interest, dividends, capital gains or taxable 529 plan distributions, there is a $1100 threshold.
