Get your taxes done using TurboTax

You can enter directly on the forms using the FORMS mode.  Click on Forms in the upper right.  You may have to drill down to the underlying worksheet to find the place to enter something.  First you need to recreate the original return.  Then when it matches each line on the original return, say you want to file it by mail so Turbo Tax thinks it was filed.  Then you can amend it.
