I’ve created my seller account a few days ago.

Hi, I’ve recently created an account and I’ve verified everything I need to. I found a product I want to list but I’m confused on shipping from said supplier to amazon warehouse. Do I just send the products to the closest warehouse or is there some extra steps to take? I’m still figuring out fba prep and such as well since I’m not sure if I should use that or not. If anyone can clarify for me that would be great.
