Hello. I'm at the last stage of filing, and it keeps on saying my EIN is invalid. I've tried everything from re-writting my address, changing it. It still doesn't work.

Your employer identification # is on your paper Form W-2 upper left corner below your SSN. Make sure that it is entered correctly in the TurboTax W-2 form under the Federal Taxes tab in Wages & Income section. You also could check the Employer's State ID # between boxes 15 and 16 on the W-2 to ensure that is entered correctly in TT in case that has anything to do with it.
