I've completed my irs forms and have saved them. I want to start the program again to double check my amended forms?

Visit the Print Center to print your tax return.

Always print a copy of your completed tax return for your records, and review it carefully before e-Filing.
You will need it if you are audited by the IRS, or to amend if a TurboTax update changes your return or for any other reason,

AND, to find your AGI next year.

This includes your revised return if you are doing an amendment.

You will need it to determine those forms and schedules that are new or changed due to your amendment.

Finally review Form 1040-X to confirm that the amounts accurately reflect your revision.

Form 1040-X becomes your new tax return.
