Answer. The code works. I needed to make sure that the first and last name fields within the wordpress admin were filled out. I filled them and the code displayed the info.

Answering my own question, I did the following to get it to work:
in the footer.php I added before the closing body tag –

jQuery(document).ready(function() {
        jQuery('input#submit').after('<i class="far fa-comments move-right"></i>');
      });

in the functions.php, I have this code –

function isa_comment_reform ($arg) {
    $textAndIcon = 'Post Comment ';
    $arg['title_reply'] = __('Leave a Comment');
    $arg['label_submit'] = __($textAndIcon); 
    $arg['class_submit'] = 'withIcon';
    return $arg;
    }
    add_filter('comment_form_defaults','isa_comment_reform');

in my header, I included this css( my style sheet is pretty long and was taking forever to save changes) –

<style>
/* overrides */
.move-right {
  position: absolute;
  margin-left: -35px;
  margin-top: 21px;
  color: #fff;
  z-index: 2000!important;
}
input[type="submit"] {
  z-index: 5!important;
}
input[value="Post Comment "] { 
  padding-right: 50px!important;
}
  </style>

And now, I have an icon in the comment Post Comment button.

Thank you for your response @wfpeter. I did put it into learning mode but was still unable to access the elementor widget. If the site was completey finished (which it isn’t) I would simply enable wordfence. If you want to poke around the site, I can set you up with the creds. Thanks again.

I simply removed the ,true from that line and the error went away. I hope this helps anyone else having this issue. Cheers.
