You cannot start over, your returns have been filed & accepted. Once your returns have been accepted, only the IRS & State can tell you when you will receive your refund. TurboTax does not get any information regarding your return or refund.
The States differ when they issue refunds.
You can check the IRS website Where's My Refund for your Federal information?
