There are actually two ways to add a category. The most common way is to go down to the categories section and click the "Add category" button. The second way is by adding them in the Classic editor of a page.

If you mean make a new category as in a brand new one, you're going to have to get an administrator's approval as it is an offense to make up new categories.
