Creating A Child Theme, CSS Not Working

I feel like I’m going round in circles here… I had a child theme on my blog (with the Twenty Twenty-Three theme) and it worked fine. I made the mistake of not keeping the files thinking I’d start afresh, since I’m completing starting over with the entire blog, but now I can’t get CSS to work in the CSS file.

I like being able to add custom colour codes/fonts in the json file so I do still need to use a child theme. I did a web browser code inspect and edited the search box there to decrease the size of it with padding but when I went to make that change in the CSS file with the .class identifier nothing happened. I’ve since tried rotating things just to see if it’s the CSS and that’s when I found it isn’t working.

This is what’s in my functions PHP file right now:

<?php
add_action( 'wp_enqueue_scripts', 'enqueue_parent_styles' );
function enqueue_parent_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
?>

And the template line from the CSS file:

Template: twentytwentythree

I must be missing something obvious but I’m not sure what. I’ve already tried taking the themes off, re-adding Twenty Twenty-Three then starting a new child theme again but that hasn’t solved it.
