Look for this in content-single-topic.php

<?php bbp_single_topic_description(); ?>

You can also use a function snippet like this to remove it for Forums and topics.

add_filter( 'bbp_get_single_forum_description', 'ja_return_blank' );

add_filter( 'bbp_get_single_topic_description', 'ja_return_blank' );

function ja_return_blank() {

    return '';
