Yes, dear!
As for Naveen - I agree with Abby and RitaB. Be respectful, make it sound like this is not usual but you've seen one or two, not surprising at his age, good for him for recognizing and stopping, but you're one of the "lucky" few and (for those who owe) we should fix this else you may well get a letter. Of course those owed refunds will be eager to amend. They will all think you walk on water, the refund people will be pleased as punch, the tax-owed folks will be glad to avoid the nasty-gram from Uncle Sam's tax boys, and no one will disparage the old preparer.
