Welcome @sunny0722, I'm not sure there is a whole lot a young adult like yourself can do to increase their height but I did find an article on the topic that offers some suggestions.

"About 80% of a person’s height depends on their genetics. After a person has reached adulthood, most tricks to increase height — such as good nutrition — will not work.
However, there are ways to appear taller and prevent loss of height, which is common as people age. This article looks at what determines height, how to prevent height loss, and more."

Have you discussed your height with your doctor to get a medical opinion?
