The new design is frustrating, but manageable.  You essentially need to create a new worksheet for each brokerage, and then fill in the information.

But I agree with you -- the old design worked perfectly fine here and I have no idea why Intuit changed it.

At first I was frustrated too, but you get used to it.  I might even like it now.  

To Intuit - Please, please bring back the Schedule D worksheet in the Quick Entry sheets.  The new format which is only available in the Forms Mode is confusing, complicated, time consuming, and a pain in the rear.
