Where in ProSeries (Does ProSeries support this disclosure) do I make the disclosure to combine the activities of a Single Economic Unit related to the Activity Grouping Rules.  I have two Real Estate Partnerships and one S Corp.  All with common ownership.  We have qualified to be combined as a Single Economic Unit to avoid the Passive Activity Loss limitations.  Where in ProSeries is the election/disclosure made? I understand the concept and want to combine the activity as one single economic unit, but I can't determine the proper way to report the activity properly.
