You do not "file an amendment" before you file your tax return. Amending is a special process you only use if you already filed the return and the IRS processed it ---and you discover after filing it that you made a mistake or left out some information. If you have not yet filed, do not click on the word "amend" anywhere.
You can make changes to the return before you file ----that is not the same thing as "amending." What do you need to change?
