Get your taxes done using TurboTax

First screen says

"Any contracts or straddles?" and "These include - Gain (or Loss) on Section 1256 Contracts Under Mark-to-Market Rules".  So I only enter trades here if I'm electing Mark-to-Market?  If I'm not electing MTM, do I enter them later?  

 

Different year, same problem.  This desperately needs programmer attention.  1256 is easy to understand and useful - why does TurboTax make this so unnecessarily difficult?
