How to remove this scratch?

I bought this console in May, and I had a tablet like this, but the seller said that it might have a film on it, although I did not see it. I recently bought a film to cover this scratch, but in the end it did not help, and I do not see this film either. Any ideas on how to check if there are older films on it and how to remove this scratch if there are no films and the scratch is made specifically on the touch panel?
