[Theme Horse Support Team]

Hi Sheik,

Show banner on homepage means you can show the banner in that page where ‘Homepage’ is set and banner on post page means it shows it on that page where you have set the page to ‘Posts Page’. You can set the ‘Homepage’ and ‘Posts Page’ via Appearance -> Customizer -> Homepage Settings.
If you are looking to show banner on posts single then you can’t do that as we have designed the theme this way.

Thank you!
