Where would I look to find this route?

Here's what I've got on my Controller:

      /**
      * @Route("/games/user/profile/{id}", name="user_profile_page")
      */
      public function userProfileAction($id){
            $member = $this->get('member.gamification.member_api')->retrieve($id, true);
            $member['participation'] =  $this->get('member.gamification.participation_api')->getUserParticipationGrouped($member['usrID'], [], true);

            return $this->checkRedirect(true, 'member/widget/gamification/'.$this->name.'/Profile/profile.html.twig', 'registration_start', array(
              'profile' => $member
            ));
      }

I know more about Laravel than I do Symfony, so my default is to be looking for a route called, "user_profile_page."

I go to the config directory where all of my .yml files are stored and, using Ransack, I start looking for "user_profile_page...."

Nothing.

What am I missing?

The fact that what I have in bold appears to be nothing more than a comment makes me think that it's not systemic as much as it's just a "note."

Where would I look for "user_profile_page?"
