The plants in my garden all all top and no bottom. The potatoes had huge beautiful leaves and grew way too big but underneath there were almost no potatoes.

You may be overfertilizing your plants, or they may be growing in extremely fertile soil. Too much nitrogen will result in lots of top growth, but very little root and stem growth. Potatoes should begin to produce tubers when flowers appear on the tops of the plants. Provide enough water to keep the soil moist without keeping it soggy wet, and hold off on fertilizer once flowering begins.

Hope your next potato harvest is bountiful!
