What is the name for the mexican sunflower that gets about 20 feet tall.

Do I cut the stems of a 20 foot tall mexican sunflower or just take off the dried flower? I have cut the stems to about 2 to 3 feet in the past but the plant is not bushy; is this the wrong thing to do???

They can handle a good pruning, so this will cause no harm. Regular deadheading will keep it healthy. You can cut the vine by about half, and it will not affect negatively in any way.

This article will give you more information about the plant (even though it is for the shorter cultivars the care will be the same): https://www.gardeningknowhow.com/ornamental/flowers/mexican-sunflower/planting-mexican-sunflowers.htm ^[1]
