Thanks for using TurboTax,
If your saying your return was rejected due to a duplicate ssn, then you must call the IRS. Go to this link http://www.irs.gov/uac/Taxpayer-Guide-to-Identity-Theft. That rejection means someone else has used your information.
Solution
Please double check all Social Security numbers in
your return against everybody's Social Security card. You can do this by
clicking the Personal Info tab and going through these screens again.
- If you come across any mistyped entries, correct them and then try e-filing again.
- Otherwise, if you verified that all Social Security numbers are correct, contact us and one of our representatives will assist you.
