I meant the frontend view of the course, somehow it showed homepage of your site instead of the course view. I can see it now 🙂
To change the icon of that price tab, you open this file:
/components/com_guru/views/guruprograms/tmpl/tabs.php
Find this tag: <i class="uk-icon-usd wk-icon-usd"></i>
and change the class as you wish.
Guru use uikit icons and you can see all list of supported icons here: /components/com_guru/css/uikit.almost-flat.min.css
There is no exact wallet icon as you mentioned, it has google wallet icon only so if I suppose that you want to change this icon, you can change above tag:
<i class="uk-icon-usd wk-icon-usd"></i>
to:
<i class="uk-icon-google-wallet"></i>
