How do I resolve this error a Section 1256 Contracts and Straddles from a K-1

This is a little odd, but yesterday I was working on taxes and had no errors.  I was getting ready to print taxes this morning, and now I have an error.

 

I have a $ 711 loss from Section 1256 contracts and straddles sales from a K-1.  It transfers to that section, but now it is asking a question on Form 6781 that I don't know how to answer.

 

I checked Box D.  The K-1 reports a Box 11 value of -711 and a ZZ code of -82.

 

How do I determine the amount of loss to be carried back?
