If you have double
checked your information and you correctly input the EIN but the return
continues to reject, then you should contact the employer or institution that
sent you the form to get the correct number, then you can go back into TurboTax
to fix it and send it back to the IRS. If you can't get it corrected,
then you will have to mail in a paper return for this year.
