<prompt> Human: I guess someone filed under my social security number before me and so I cant file. TurboTax says to file paper and Ill get a form back from the IRS. Is that really all I can do for now?Edit: So many helpful comments. Thank you all very much.  <response>: TurboTax says to file paper...Yes. You will have to paper file by mail. Youre locked out of e-filing if someone else has already used your SSN.
