I don't have any contracts or straddles but TurboTax is showing me an amount of $60 in that category. How do I check where that amount comes from?

You can check any K-1 probably from a partnership and see if there are any type of transactions that passed through to you personally. Check Box 11 Other Income.

Also check Box 11 on a 1099-B.

Under Investment Income, click Start/Update on "Contracts and Straddles"

Select Contracts and Straddles - answer yes to Any Straddles or section 1256 contracts, don't check any elections (unless they apply to your situation), check the box Section 1256 contracts market to market, continue through the interview. 

You will find that TurboTax offers only two boxes for Line 11 (gain or loss) and that is all that has to be entered.
