To properly edit an accounts DocumentRoot go to /var/cpanel/userdata/username/ (replace username with the actual cPanel username for the account), then edit the file domain.com (where domain.com is your primary domain name).
You will see something like this in that file:
documentroot: /home/username/public_html
You will also see the cgi-bin area in this section:
