After you file

If you have not already filed you may be able to "Clear and Start Over."  In the left-hand column choose "TAX TOOLS" then "TOOLS"===>"Clear and Start Over"

If you have filed the return and the return contains incorrect or incomplete information taxpayers file an amended return (1040X).  Allow time for the original return to be fully processed by the IRS prior to filing the amended return.  TTX will guide you through the Amended return process.  NOTE: Amended Returns are "Old School"  Print/Date/Sign/Mail---no efiles available.
