After you file

@B5407v   There is another way to get to amend.   Open and continue your accepted return.  If you don't see a button for Need to Amend a Filed Return? on your home screen then you can get to it here. Go to:

Federal Taxes -or- Personal (for H&B)
Other Tax Situations
last section, Other Tax Forms
Amend A Return - Click the Start or Update button

 

But first you should save your return with another name to make a copy to amend so you don’t change your actual return.   Go up to File-Save As (Duplicate on Mac).
