How do I report duty-free if it doesn't exceed 600 dollars when I report customs?

Including what I bought at the duty-free shop, it's about 300 dollars.

I heard that if it doesn't exceed 600 dollars, it's duty-free.

How do I report it if it doesn't exceed 600 dollars?

Or do you just come in without doing it?
