The mod settings can be found at the main menu, on NTerraria 6, on the lower part of the screen, It has it's own button on the bottommost part of the window.

On NT3, I believe It's inside Terraria settings menu.

In case you are talking about the settings file, go to My Documents/My Games, open the folder of the mod season, and you'll find the config file inside.
