I think I found the bug !!! Had a T3 and inserted information in the Foreign income box (which I later deleted that information). But I had put down source of Foreign income as "USA" (assumed this was for a US ETF. Anyways, the fact that there is a Foreign Income "USA" noted, seems to trigger all of the self-employment/business income nonsense. When I reset the "source of foreign income" drop down, to nil, then I could immediately file via NETfile. An obvious bug in the software.
