After a lot of running around and looking everywhere!!!! I finally was in the right area and saw on the map a flashing circle over a guy on the map. I ran over there and into a doorway that I didn't remember and found the guy who was keeping me from leveling up.
If you are stuck as well you might want to check it out. The cool thing was that I noticed the quest guy highlighted in yellow (see below) while I was screen capping the location of the UFO!
