How can I remove a spam page from my website index?

Hello @DaveSweetCures and @gregbernhardt , I need clarification on steps 4 and 5. It is my understanding that the Google Disavow Tool is for Spammy backlinks from OTHER sites pointing to your site as opposed to Spammy links ON YOUR SITE, which is the case here. In other words, you are disavowing a URL on your own site, not from an outside site. Could you please clarify how to use this tool for this specific issue? Thanks for your help!
