IRS stated they have not received my taxes ....

Again filed early weeks ago ..... TurboTax says my Federal was accepted weeks ago .   IRS website and IRS agent I spoke to say they have not received my return yet ..... so which one is it?.   Only thing possible is that the refund amount TurboTax shows me is different from the amount sent to the IRS due to using my refund to pay.  Any guidance would be lovely.
