Yes, you can use the mileage provided by Uber definitely if it contains your waiting and picking-up mileage, provided you are comfortable with what is being reported to you. From what you said above about Lyft, I might want to consider keeping a log of your Lyft mileage provided you trust your Uber mileage. As a suggestion, I would try to keep as much of a log as I could to be able to compare what Uber and Lyft are saying in their statements and what you yourself know based on any log you keep.
