Change copyright line (Customizr)

My site is: https://leadwithhorses.com/

I have read the forums on this topic, but am still struggling to change the copyright on the bottom of the page (white footer, below gray footer). I am using the newest version of Customizr, 3.3.1, and do not see a class-main-footer.php file. I can only find the footer.php with the following:

<?php
/**
* The template for displaying the footer.
*
*
* @package Customizr
* @since Customizr 3.0
*/
do_action( ‘__before_footer’ ); ?>
<!– FOOTER –>
<footer id=”footer” class=”<?php echo tc__f(‘tc_footer_classes’, ”) ?>”>
<?php do_action( ‘__footer’ ); // hook of footer widget and colophon?>
</footer>
<?php
wp_footer(); //do not remove, used by the theme and many plugins
do_action( ‘__after_footer’ ); ?>
</body>
<?php do_action( ‘__after_body’ ); ?>
</html>
