Try googling turtle and the name of your state for links
Also check out the link below.
In many states you cannot remove a turtle even on a golf course (just move it out of harm's way) without having a valid and current fishing license or a reptile license.
Also check out turtle societies as there may be one near you.
In a pinch find a store that sells live bait and get some earthworms or grubs-mealworms may be available at a pet shop but these may not be taken by the little turtle-get the worms!!! And good luck-TURTLES ARE COOL!
Also do not keep in a terrarium. Got a large pan with straight walls that it cannot climb out of. Put in a deep layer of sand and a large bowl with a large rock that it can climb out on if it enters the water. Put in a partially sunny spot where there is some direct sun during the day as turtles need sunlight for their shells to develop correctly.

As mentioned above turtles need exposure to UVB/A light. A common pet store will have a reptile light that would work. Most if not all turtles need a basking lamp as well, where they can get out of the water and completely dry off to avoid shell issues ( aquatic turtles ).

From the description it could be a painted, or red eared slider. Does it have red markings, where its 'ears' would be? If so thats an aquatic turtle. Since it he was wild caught, the idea of getting worms or something at a bait shop would work. But to avoid any pathogens from bait shops, most pet stores sell crickets ( a dozen for like .75 cents ) which he will devour. Turtles are messy eaters, if it is indeed an aquatic turtle, make sure you have the proper filtration or siphon the tank weekly. You should also dust the crickets with some sort of Vitamin dust to provide proper nutrients. Just go to your local pet store and ask for some info, they'll direct you in the right place.

Do some research, you can google both Red Eared sliders, and painted turtles and come up with alot of websites that will provide information. Just make sure to provide the proper lighting requirements so you don't get any shell fungus.
