I got an error message saying: "Employer identification number (Box b) of Form W-2 and/or W-2GU..."
If your return was rejected because a number is incorrect, it’s probably a simple typo or something that was put in the wrong spot. It’s OK. It happens. Just select the Make Changes button next to that item on the Tax Summary screen. Once you’ve made the fix, continue to the end of TurboTax and re-send your return. It’s that simple!
