Analytics Code Appearing on Home Page

Question

For some reason the code of Google Analytics is appearing on the home page of a client of mine and I am not able to remove it from there. And at the same time, obviously, I need it to keep working.

The code went like this:onClick="ga('send', 'event', 'Forms', 'Click');"

It was inserted at the end of the HTML editor inside the CMS. All the content below is inside the BODY tag. And it was like this:

<script type="text/javascript" async src="https://d335luupugsy2.cloudfront.net/js/loader-scripts/2c4203a9-ed9e-4af1-94f8-d40cb871826f-loader.js" ></script>
<script type="text/javascript" src="https://d335luupugsy2.cloudfront.net/js/integration/stable/rd-js-integration.min.js"></script>
<script src="https://code.jquery.com/jquery-2.2.4.min.js" integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44=" crossorigin="anonymous"></script>
<script type="text/javascript">

function sendContactToRD(event){
  event.preventDefault();
  var form = jQuery(event.target).closest('form');
  var data_array = form.find(':input').serializeArray();
  data_array.push(
    { name: 'identificador', value: 'Contato' },
    { name: 'token_rdstation', value: '3b186d9de846a1105cb4fe3ef63b8e95' }
  );
  RdIntegration.post(data_array, function(){
    buttonContato.unbind('click', sendContactToRD).click();
    buttonContato.bind('click', sendContactToRD);
    return false;
  });
}

jQuery(document).ready(function(){
buttonContato = jQuery(':submit');
buttonContato.bind('click', sendContactToRD);
});
</script>

<script type="text/javascript">

var google_conversion_id = 968350051;
var google_conversion_language = "en";
var google_conversion_format = "3";
var google_conversion_color = "ffffff";
var google_conversion_label = "j1WcCImatnIQ47LfzQM";
var google_remarketing_only = false;
/* ]]> */

</div>
</noscript>

onClick="ga('send', 'event', 'Forms', 'Click');"

And finally, the code appears there in the upper left corner of the home page that way:

I already apologize if it’s a stupid question (I couldn’t find a solution in Google) or anything else stupid, this is my first topic. Thank you in advance.
