I couldn't find Google's "Fact Check" but did find an article indicating that Google has apparently removed it, stating:

"We said previously that we encountered challenges in our systems that maps fact checks to publishers, and on further examination it’s clear that we are unable to deliver the quality we’d like for users....Fact checks from independent organizations will still appear alongside articles in search and Google News. "
