reCaptcha not showing in Leave a Comment

We are using Theme1986 running WordPress 4.9.8
The theme is fairly simple.
I installed reCAPTCHA in WP comments plugin but I do not see the reCaptcha in the “Leave a Comment” section.
I can see that the theme has comments.php file
I have read a number of other comments in this forum but I have not seen something that solves my issue.
I have implement reCaptcha successfully with the plug in “Contact Form 7” plugin
To stop spam I have set that users must be logged in to leave a comment. If you want to log in I have setup a temporary user with id = xrmlabs and password = cPh!D%2Yp@8JL09@N#dfpc)* so you can see the “Leave a Comment” form.
Can you advise what I need to change.
thank you

The comments.php file looks like this:
<?php
/**

* @subpackage theme1986
*/

// Do not delete these lines
if (!empty($_SERVER[‘SCRIPT_FILENAME’]) && ‘comments.php’ == basename($_SERVER[‘SCRIPT_FILENAME’]))
die (‘Please do not load this page directly. Thanks!’);

if ( post_password_required() ) { ?>
<?php echo ‘<p class=”nocomments”>’ . __(‘This post is password protected. Enter the password to view comments.’, ‘theme1986’) . ‘</p>’; ?>
<?php
return;
}
?>

<?php wp_list_comments(‘type=comment&callback=mytheme_comment’); ?>

<?php else : // this is displayed if there are no comments so far ?>
