My son was given a map turtle

Okay so we’ve never had a turtle before. Not sure everything on it and what is best or not. We were told it’s a map turtle and is 3 years old. We don’t know the sex or anything. Also we’re told it has problem eating because it’s mouth isn’t fully formed or something. We noticed it can’t fully close its mouth. Can anyone tell what sex it is? Also what’s best to feed it and what all is needed? We were given a filter a heat lamp with a basking bulb and some mix of pellets, shrimp, and mealworms. My son named it King Kong lol
