I can't install drivers on Linux Mint 20

Hello, I can’t install the driver for GTX 1660 Ti on Linux mint 20. I have tried running the file the downloaded file and it literally does nothing if I try and run it in the terminal or if I exit any x server process and run it like that, driver manager doesn’t see any driver now and previously just ran into errors telling me files were missing, sudo autoinstall also did not work bc after it finished I tried nvidia-smi and it told me it can’t contact the driver. Please, if someone has any answers to this let me know. I am literally going insane.
