hi levi0322,
Just add this functions inside functions.php at the top of the page.

<?php

add_action( 'wp_enqueue_scripts', 'enqueue_child_theme_styles', PHP_INT_MAX);
function enqueue_child_theme_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
    wp_enqueue_style( 'child-style', get_stylesheet_uri(), array('parent-style')  );
}

make sure that your child theme is created or not and from dashboard -> appearance -> themes

If yes then activate the child theme first. Once send you site url too. If still you are unable then you need to hire a developer. Because we don’t ask ftp. And from the dashboard only its not possible to customise the code.

Thank you!
