After you file

My return has been in pending for 3 days. I realized when Turbo prompted me for a new PIN I entered PIN that was different from my last  year's PIN and I don't know if this was the reason the it is still in pending.  Also I am using a new email that has never been used with TurboTax before. The status given by TurboTax makes me think they received it but has not transmitted to the IRS. It says this. I am worried that my return will be late for April 18 if the IRS has not received by then.
