Get your taxes done using TurboTax

I have checked with the employer.  They swear it is correct.  It was correct last year.  I was paid by a different employer that uses Quickbooks.  Turbotax downloaded the info and they got a new EIN(different than the W2).  It was the same with two new digits added on the front.  How do I find out what two digits to add to my wife's employer's ID?
