Hi Crissy,
welcome to the forum. If your calves are bigger than your upper legs, building up msucles in your quads and hams would help. Do you belong to a gym? On this page you can click on quads and hamstring to find various exercises. Also abs since you want to work on your tummy.

And actually, it would be best if you worked all your msucle groups for balanced strength.
But don't worry, doing these exercises will NOT make you musclular like them! Chances are they have been training hard for years and have taken some performance enhancing supplements...
These exercises will not help you lose fat in those particular areas. Fat comes off the body evenly all over. Here's some info on that:
• Fat loss will occur in a preprogrammed proportion dependent upon genetics, sex, and hormonal levels.
o Areas with the largest amount of fat lose more fat although although these areas will seem to be totally reduced last.
o With adequate fat loss muscular definition will be achieved in the peripheral and gradually toward the waist, hips, or thighs.
• Exercise will help burn calories and maintain lean body weight which can result in fat loss. Increases in muscle in specific areas can change the appearance of those areas but will not result in specific loss of body fat.
• If the muscle mass improvements out pace fat loss in a specific area, girth can be greater.
I hope that helps.
