Adding New Product to Catalog, where is it?

So I’m trying to add my own FBM products to my sellercentral. I submit, and then where is it? Do I need to wait for it to be added to amazon’s catalog before I can list it? I’ve tried adding a product twice now, and I don’t understand where it goes or when it shows up or what I’m missing? This is not explained anywhere. I have my GTIN exemption, there are no errors or red ! anywhere, I submit and then there’s nothing on my dashboard and it’s prompting me to add my first product, and I’m like, I just did.
