Overcoming Rejection of E-filed IRS Form-1040

I've used TurboTax for years.  This year my e-filed federal 1040 was rejected numerous times.  Every possible entry has always been correctly entered each I attempted to re-file - never had I entered anything incorrectly.  Am I stuck with having to mail via USPS?  I would appreciate speaking directly with one of TurboTax's experts to overcome this frustrating situation.  Archie
