After you file

I fully understand all that. I'm being as clear as I can. How long does it take from when I push the "file my taxes" button in TurboTax until they are ACCEPTED or RECEIVED? I'm not asking about anything that happens after it's accepted or received. I don't care how long it takes for processing or how long it takes to get the refund. How long does electronic submission and receipt/acceptance happen? This is the question.
