If you received Reject Code R0000-902-01: Taxpayer TIN In Return Header Must Not Be Same As TIN of Previous E-File, this means a return has already been filed under your social security number. If you did not file your return and do not know anyone who is entitled to file you as a dependent, you will need to notify the IRS that another return has been filed with your social security number by filing form 14039.
You will need to print, sign and mail your return and the form for processing.
