Get your taxes done using TurboTax

Thanks for the all replies. All my questions are answered except one last 1.

How do I file amendment using Turbotax?. Where do I enter carryback amount (in turbotax online) while preparing amendment. I went thro the questionnaire again. I didn't see any question related to "Carryback" for 1256 contracts.

Do I have to go to tax professional or do it thro Turbotax?
