Is 1913 to many calories for a 14 year old girl who is 5'6?

No. While it is on the higher side of what is recommended for that general age and height group (the range is wide, from 1,400 to 2,000 calories), about 1,900 calories is especially good if she is active or participates in sports, or other hobbies that keep the body moving. It is also very good if the calories come from healthier foods and bevarages, and not too many from fats or sugars.
