Have you already filed your return?  What state are you living in?  If you have not filed your return, you can go back and delete the incorrect information.

If you've filed your return and need to add additional information, then you will have to prepare an amended return in TurboTax.  I suggest you wait at least 3 weeks before sending it to ensure that the IRS does not confuse the returns.  You have three years to file an amended return.

If you used TurboTax Online, simply log in to your account and select “Amend a return that was filed and accepted.” 

If you used our CD/download product, sign back into your return and select “Amend a filed return.” You must file a separate Form 1040X for each tax return you are amending.

You will have to mail the amended return.  The IRS limits the system to only one Social Security number or Tax ID  to be E-Filed.  This is to guard against fraudulent tax returns.
