Did you efile? Was it Accepted? You can check your efile status here <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/tax-tools/efile-status-lookup/">https://turbotax.intuit.com/tax-tools/efile-status-lookup/</a>
Then what does the IRS say? IRS Where's my refund <a rel="nofollow" target="_blank" href="https://www.irs.gov/refunds/">https://www.irs.gov/refunds/</a>
Make sure you are using the refund amount from your actual federal tax return and not the combined amount Turbo Tax showed you at the end. That was for federal and state combined.
When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc. what does it say?
