Help to add reflections

Hey guys!

So I'm new in development. Im in the middle of a coding school. I created a token using another tokens contract as a baseline. I deployed the contract but am having trouble knowing if the reflections are set up. I believe there are functions to add reflections or are they already set up? Can yall check it out and let me know please before I start marketing!

Here is a link to the contract through bscscan:
