creating my first listing, need help!

I got the product manufactured, bought the UPC for it, started creating the listing, and added the brand name (I have that mentioned on the product) where it says Brand Name. Click on next. it says this message:

Brand Authorization Required: The ability to create or edit ASINs using this brand name is restricted to authorized sellers. You need to apply for approval to add or modify products for this brand.

I don’t have an LLC, would it ask me later on for LLC information too if I click on “apply for sell”

or should I just keep it Generic and it doesn’t matter the brand name.
