How to register sidebar on taxonomy template pages?

I have a bunch of taxonomy-something.php pages that currently have blank sidebars–they’re not inheriting the sidebars with widgets that Posts within the theme have.

How would I need to modify the code below to allow for sidebar widgets on taxonomy pages?

/**
 * register sidebar
 */
if ( ! function_exists( 'maple_ruby_register_sidebar' ) ) {
	function maple_ruby_register_sidebar() {

		if ( get_option( 'tn_custom_multi_sidebars', false ) ) {
			$current_sidebar = get_option( 'tn_custom_multi_sidebars', '' );
			if ( is_array( $current_sidebar ) ) {
				foreach ( $current_sidebar as $sidebar ) {
					register_sidebar( array(
						'name'          => $sidebar['name'],
						'id'            => $sidebar['id'],
						'before_widget' => '<section id="%1$s" class="widget %2$s">',
						'after_widget'  => '</section>',
						'before_title'  => '<div class="widget-title"><h3>',
						'after_title'   => '</h3></div>'
					) );
				}
			}
		}

		register_sidebar( array(
			'name'          => esc_html__( 'Full Width Top Footer', 'maple' ),
			'id'            => 'tn_sidebar_top_footer',
			'description'   => esc_html__( 'Full width area at top of footer area. Only allow {TOP FOOTER WIDGET] & custom html widgets.', 'maple' ),
			'before_widget' => '<section id="%1$s" class="widget %2$s">',
			'after_widget'  => '</section>',
			'before_title'  => '<div class="widget-title"><div class="widget-title-inner"><h3>',
			'after_title'   => '</h3></div></div>'
		) );

		register_sidebar( array(
			'name'          => esc_html__( 'Footer 1', 'maple' ),
			'id'            => 'tn_sidebar_footer_1',
			'description'   => esc_html__( 'One of column of footer area', 'maple' ),
			'before_widget' => '<section id="%1$s" class="widget %2$s">',
			'after_widget'  => '</section>',
			'before_title'  => '<div class="widget-title"><h3>',
			'after_title'   => '</h3></div>'
		) );

		register_sidebar( array(
			'name'          => esc_html__( 'Footer 2', 'maple' ),
			'id'            => 'tn_sidebar_footer_2',
			'description'   => esc_html__( 'One of column of footer area', 'maple' ),
			'before_widget' => '<section id="%1$s" class="widget %2$s">',
			'after_widget'  => '</section>',
			'before_title'  => '<div class="widget-title"><h3>',
			'after_title'   => '</h3></div>'
		) );

		register_sidebar( array(
			'name'          => esc_html__( 'Footer 3', 'maple' ),
			'id'            => 'tn_sidebar_footer_3',
			'description'   => esc_html__( 'One of column of footer area', 'maple' ),
			'before_widget' => '<section id="%1$s" class="widget %2$s">',
			'after_widget'  => '</section>',
			'before_title'  => '<div class="widget-title"><div class="widget-title-inner"><h3>',
			'after_title'   => '</h3></div></div>'
		) );
	}
}

add_action( 'widgets_init', 'maple_ruby_register_sidebar' );
