Humminbird how to erase track

I have a Humminbird Helix 12 Mega. I transferred all my data from my old 1197c. I have tracks that transferred over that I would like to erase. How do I find a track and erase it?

Put your cursor on the track and hit the check mark button. Options will come up. Can also go to the waypoints and tracks menu and delete the tracks through it
