Positioning a sidebar on the side

I have set up a custom template for one of my site pages. On this page, I want to have a sidebar. Right now I am using a child theme of twenty-twenty. I tried to copy the tags from twenty seventeen on my sidebar file but it displays the sidebar at the bottom of the page. I need help displaying the sidebar on the right-hand side of the page.

This is the code of my sidebar php file.

<div id="sidebar-kgm-filters" class="sidebar">
	<aside id="secondary" class="sidebar" role="complementary">
		<?php dynamic_sidebar( 'kgm-filters' ); ?>
	</aside>
</div>

This is the code of my template php file.

<?php
/**
 * Template Name: Courses Template
 * Template Post Type: post, page
 *
 * @package WordPress
 * @subpackage Twenty_Twenty
 * @since Twenty Twenty 1.0
 */

get_header();
?>

<main id="site-content" role="main">

	<?php
    
	$archive_title    = '';
	$archive_subtitle = '';

	if ( is_search() ) {
		global $wp_query;

	}

	if ( have_posts() ) {
        
		$i = 0;

		while ( have_posts() ) {
			$i++;
			if ( $i > 1 ) {
				echo '<hr class="post-separator styled-separator is-style-wide section-inner" aria-hidden="true" />';
			}
			the_post();

			get_template_part( 'template-parts/content', get_post_type() );

		}
	} elseif ( is_search() ) {
		?>

		<div class="no-search-results-form section-inner thin">

			<?php
			get_search_form(
				array(
					'label' => __( 'search again', 'twentytwenty' ),
				)
			);
			?>

		</div><!-- .no-search-results -->

		<?php
	}
	?>

	<?php get_template_part( 'template-parts/pagination' ); ?>
    <?php get_sidebar( 'kgm-filters' ); ?>
</main><!-- #site-content -->

<?php get_template_part( 'template-parts/footer-menus-widgets' ); ?>

<?php
get_footer();
