The problem with revealing your estimate is it’s just an “estimate”, it's your best guess for that job, that the GC will then use against you. If you guess high it’s your gain, but of you guess low it’s your loss, and that info is private. If the GC wants T&M rates, then give him that, but your takeoff is proprietary, especially if you don’t have a contact.
However on bigger jobs you may be required to provide a detailed breakdown for change orders, but this would be a job you already have a contract on, and even then being vague is a good thing.
