You do realize, of course, that Intuit programmers go to H&R Block for their own returns.  It doesn't do much good to explain (for example) that CA SDI in Box 14 should be entered for those who itemize, and does go to state taxes -- but that other items shown there are not in the same category. 

I just did a return with Housing Allowance listed there.  (Church W-2; taxpayer is clergy.)  Now I'm wondering, just hypothetically, whether union dues on a clergy return could be used as a deduction for self-employment tax.  That would be fun to explain to a programmer.  And yes, the clergy do have unions in Great Britain and Canada.  Not sure about this country, yet.
