Cleaned up basic customization below. The $_REQUEST['post_id'] is the same as the $post_id provided in the arguments.

function custom_relationship_query( $args, $field, $post_id ) {
	$args['tax_query'] = [
		[
			'taxonomy' => 'custom_taxonomy_name',
			'field'    => 'term_id',
			'terms'    => str_replace( 'term_', '', $post_id ),
		],
	];
	return $args;
}
add_filter('acf/fields/relationship/query', 'custom_relationship_query', 10, 3);
