Importing Spouse's 1099-B.

I'm filing jointly with my spouse.

When I import Spouse' 1099-B, Turbo Tax would not ask if it is for me or for my spouse. 

After I import it, if I look at the Capital Asset Sales Worksheet, it's under my SS# and both of our names.

How do I separate it?

There is option to change the ownership for DIV & INT, but not for 1099-B.

Only way to update seems to be going to Forms and directly update Capital Asset Sales Worksheet.  This is odd. and seems like Turbo Tax needs to correct this.
