I don't see that option. :(

I think this appears only when the Adsense code is used outside of your allowed sites. It is labeled as

Unauthorized Sites. The following sites are not on your Allowed Sites list but have displayed ads using your AdSense publisher ID within the last week.

Funny thing is that for us, it includes a Russian site as well as legit ones like

Bing Translator
translate.google.com.hk
translate.google.com.pe
translate.google.co.in

We have the old interface, and it is in Adsense Setup --> Allowed Sites, which is broken into two sections: Allowed Sites and Unauthorized Sites
