I went to the IRS website to check on the status of my return not only does it say its not approved, but it also says that they havent even received it. Can someone help?

TurboTax says its been filed and approved, I understand that means, in TurboTax's eyes, the irs has my tax forms. However when I went to check it they haven't received my tax forms. I filed my taxes a 2 weeks before my friend and he got his approval and return from the irs faster. I don't know whats going on and could really use some answers.
