Form 8949 Box C entries for a fiduciary return?

[Thorgils]

I'm completing a Form 1041 return, but can't identify a route to creating a Box C entry in an associated Form 8949.  I have proceeds from a class action that should be classified as a short-term gain, but with no 1099-B entry.  Please advise.

Enter the class action amount as though you did receive a 1099-B, as investment income, to complete your return. Be sure to enter dates that would reflect short term holding period (less than one year. Enter zero as the selling price and the loss as the cost basis. Also you can label it as 'Class Action Settlement'.
