New User Stuck on Blue Kodi Category Page, Can't Get Out

Yes, I’m new & I’ve had Kodi up and running for 3-4 days. I was checking out the menu & got stuck with the Kodi selection page. Categories on the Left in black are listed top to bottom

Movies
TV Shows
Music
etc,

Over in the center of the page in blue there’s a message says

                   Your Library is currently empty etc,,, 3 sentences long.

                   2 Choices enclosed in dark blue boxes

                   Enter files section         Remove this main menu item 

When I turn Kodi on, I get the advertisement page & select Settings to open Kodi no problem. Except instead of getting program selections I get this blue menu screen. I know this is very silly & probably obvious, but if you know how to get me back on track & watching Amazon again I’ll owe you Bigly, thanks

Take a photo so we can see what you mean

What device are you running on? OSMC provides no method of watching Amazon content.
