First, let us get this straight :
1. Adsense earnings that came from the HubPages can be seen only in the Adsense Interface.
2. Earnings that came from the HubPages Ad program can be seen in the Hubpages Ad reports.
3. Now, to see the Adsense earnings in your Adsense interface, you should have configured the same from the Hubpages Affiliate settings page.
Go to my account==>Earnings==>Affiliate Settings==> configure .
Give your Adsense code and you are done. Now you should be able to see your Adsense earnings both from your site and the Hubpages in your Adsense interface.
Hope it helps.
(If you have done the third step and still not able to see the HP earnings in your reports means, check the access and authorization section in the Account Settings in the Adsense interface and do any minor tweaking needed.)
