Are you using the Online web version or the Desktop CD/Download program?
in the Desktop program you can try sorting.
If you are using the desktop version you can go to forms Schedule B and when you're on the list go to menu item Edit and there should be a Sort Table selection.
Seems to only let you sort the Interest table and not the Dividend listing.
In the Windows Desktop program you can sort the dividends in the interview step by step mode just by clicking the Broker or Payer column heading.
