Answer
You should bring your bird to a qualified bird veterinarian.  This is a serious problem and needs to be seen by a vet for proper diagnosis and treatment.  You'll have to find a vet that's experienced with birds, as most regular dog & cat vets don't have much expertise when it comes to our bird friends.

Overgrown beaks can be caused by several things, including old injuries, dietary deficiencies, and Knemidocoptes mites.  A vet will be able to diagnose the problem, as well as trim the beak so the bird is able to eat properly.  The bird may need regular beak trims in the future, too.  Your vet should be able to show you how to do it at home if you don't want to take the bird in regularly.

Sorry I couldn't help more.  This just isn't the sort of problem that can be diagnosed or treated over the internet.
