How to change where the confirmation email is sent
Take a look at Contributions -> Manage Contribution Pages, choose the relevant page, and then click on Configure, all  the way over on the right. Then take a look at Receipt for that page, 
might be at 
https://[your_website]/civicrm/admin/contribute/amount?action=update&amp;reset=1&amp;id=1
and the e-mail addresses that a receipt is cc'd and bcc'd to.
