How to show custom data on custom post type admin screen edit page?

I have created form for enquiry. When user fill this form then I am saving it into database as a custom post type. In backend I need to show extra information on custom post edit page. But did not find any hook.

I have tried this code:

[![function add_extra_info_column( $columns ) {
    return array_merge( $columns, 
        array( 'sticky' => __( 'Extra Info', 'your_text_domain' ) ) );
}
add_filter( 'manage_posts_columns' , 'add_extra_info_column' );][1]][1] 

But it adds a new column in custom post.

I need to show extra info when we click on edit page link for every post.
