TurboTax e-file

Hello:

Early this morning (about 5 hours ago), I e-filed my Federal and state taxes through TurboTax desktop.  I hit the "transmit" button, it seemed to transmit and then stopped, with no notification of any kind.  I have not received any email notice, except a receipt for the state e-filing fee from Intuit.  When in TurboTax, I look at "check filing", TurboTax says I haven't e-filed anything.  I hesitate to transmit a second time, for fear that IRS will get 2 identical copies and cause all sorts of headaches.  Yes to transmit a second time, or wait??

Thanks.
