Buddy, if you know more than me, then why you asking your questions? :smirk:

Once again. If you need to install a plugin within your theme using TGMPA, then you should use get_template_directory()

I.e.

array(
            'name'               => esc_html__( 'My Meta Boxes', 'textdomain' ), // The plugin name.
            'slug'               => 'pretty-awesome-meta-box', // The plugin slug (typically the folder name).
            'source'             => get_template_directory() . '/inc/plugins/pretty-awesome-meta-box.zip', // The plugin source.
           .............
        )
