How to change to link (taxonomy)

I am using ReviewIt template. When I add another field to review like this https://themeforest.net/item/reviewit-review-community-wordpress-theme/full_screen_preview/109666, I want to show link to buy this DVD (go straight to amazon), but all links has a view like “https://ghostpool.com/wordpress/reviewit/studio/fox-searchlight-pictures/”, but I need “https://amazon.com/item89773w”.

Where can I change it?

there is a file review-container.php, where I see a line, for example:
<?php echo(get_the_term_list($post->ID, ‘studio’, ‘

• Studio: ‘, ‘, ‘, ‘

‘)); ?>

another file connected to this is theme-post-type.php:
register_taxonomy(‘studio’, ‘review’, array(‘hierarchical’ => false, ‘labels’ => array(‘name’ => __( ‘Studios’ ), ‘singular_label’ => __(‘Studio’), ‘add_new_item’ => __( ‘Add New Studio’ ), ‘search_items’ => __( ‘Search Studios’ )), ‘rewrite’ => array(‘slug’ => ‘studio’)));
