display specific category on page

Just use WP_QUERY to achieve that.

<?php if ( have_posts() ) : ?>
    <header class="page-header" style="animation-delay: 0.3s; animation-duration: 2s;">
        <?php
            the_archive_title( '<h1 class="page-title">', '</h1>' );
            the_archive_description( '<div class="taxonomy-description">', '</div>' );
        ?>
    </header>

    <div id="archive-blog-wrapper" class="archive-blog-wrapper three-columns">

        <?php /* Start the Loop */ ?>
        <?php
        //set up a new query
        $category_query=new wp_query( array( 'cat' => 'put your category id here');

      while ( $category_query->have_posts() ) : the_post(); ?>
            <?php
                /* Include the Post-Format-specific template for the content.
                 * If you want to override this in a child theme, then include a file
                 * called content-___.php (where ___ is the Post Format name) and that will be used instead.
                 */
                get_template_part( 'content', get_post_format() );
            ?>
        <?php endwhile; ?>
    </div><!-- archive-blog-wrapper -->

    <?php rock_star_content_nav( 'nav-below' ); ?>

<?php else : ?>

    <?php get_template_part( 'content', 'none' ); ?>

<?php endif; ?>
