TurboTax said I sold investments other than stocks and bonds, but I didn't.

TurboTax said I sold investments other than stocks and bonds, but I didn't. 

 

So, I searched around, and found out it's from K-1, 100 shares of stock DBC.  In K-1, line 11 C (Sec. 1256 contracts and straddles), I received $28 as other income.  I hate K-1, but it's too late to sell it now.

 

If I remove this $28 other income in line 11C, my total tax liability doesn't change at all.

I can add this $28 gain to schedule D, too, because DBC  is really a stock. 

 

Thanks in advance.
