The deleted scenes included on The Force Awakens Blu-Ray have been revealed, and there looks to be six in total.
These come from JB HiFi and appear to be legit as they match up with things that were filmed:
Finn And The Villager
X-wings Prepare For Lightspeed
Kylo Searches The Falcon
Snow Speeder Chase
Finn Will Be Fine
You can see a preview of the Kylo scene in the trailer Lucasfilm released for the Blu-Ray. We know the Snow Speeder Chase was filmed and you can see Rey and Finn getting out of that speeder in the finished movie.
