After you file

When you follow the procedure to amend your tax return as shown in the Support FAQ for amending a 2016 tax return, the program provides the Form 1040X and other associated forms that are required for mailing to the IRS.  You just print and mail the Form 1040X and other forms, sign and date the Form 1040X and mail to the IRS.  The address on where to mail will be included in the Filing Instructions.
