After you file

This is the second year in a row that this has happened.  Every time the IRS transfers me to what they think is the correct extenstion, "There is no one available to help you.  Try another day."  I have tried about 900 times.

 

The IRS website says that it cannot process my request. 

What else can I do to verify my identity?  TurboTax should provide assistance for this.
