RE: The IRS requires all 4 pages to be submitted, even when there isn't any information on that page.

Need more info.  Source?

Instructions for Part II (Page 3):

Part II
Complete Part II if you checked box (2) or (4) in Part I, item F.

I imagine Lacerte has interpreted it as "No need to include Part II if it isn't applicable".  I've filed F2553 without part II (page 3) all these years.  There has not been a problem.
