FYI - Screen 22 Category really only serves a purpose if you are trying to match up to financial statements. It has no real function in the tax program. 

Screen 29 - Did you enter the business use area and the total area of home? Did you indicate the activity number (probably 1= the Sch C business name)

If you restore from C:\Lacerte\20Tax\demodata and select Sample07 it is a demo return for Office in Home. Any client with ssn or ein of all 9's can be "played with" with no REP fee, but you do may need to do the REP.
