As others have noted, contact your school and potentially past teachers. If they used TurnItIn, the teachers would likely be able to recover your paper (although maybe not comments - depends on the teacher and how TurnItIn was set up and used).
Turning in the paper that you sent to your dad could work if you don’t have a good paper in the next 2 months from your new school.
fwiw, my youngest (1st year at Princeton) turned in an A- history paper with no teacher comments plus the writing prompt. It was a good writing sample and, at the very least, did not put my kid in the “reject” pile.
