I entered an incorrect SSN and then filed. Cannot get back in to correct it. Please advise.

You can get back into your return using the steps here below.

• Log into your TurboTax account and click My TurboTax at the top
• You should be on the Tax Timeline now
• Scroll down to SOME THINGS YOU CAN DO section
• Click Add a state (not really adding one, just a way to get back into return) 
• Once inside the return, click Personal Info tab and then Edit next to your name (or name of person that needs correction) on that screen and correct social there.
• Then go back to File tab and go through to resubmit the return. 
• NOTE: Do not select "Fix my return" here (you've already done that).
