Custom Single Post

Hello

I have installed the Meta Box plugin to create custom fields and custom post types. I need to display their fields in the front end, however they state to copy the single.php and rename as single-{post-type}.php in child theme. Problem is, I can’t find the single.php in the OWP theme directory. I’ve tried using hierarchy structure as stated in some of the theme files as partials/single/layout or partials/single/content, and placing my code in there, but this does nothing.

Where do I find single.php in the theme files, or how do I create my own custom post type .php file to overwrite this post type in my child theme?

Thank you
