I'm working in ProSeries Basic, reporting disposition of a vehicle for which we've been claiming actual expenses.  Business use has varied over the years.  I've calculated the overall business use (it's well over 50%) and apportioned the sale between business and personal.  Taking into account the $25000 Sec 179 deduction, the special depreciation allowance, and the ordinary depreciation, I believe I should have a gain of over $20K.  But ProSeries is giving me a much lower gain and the depreciation doesn't show up on the 4797.  I can't see how it's coming up with the figures it's giving me.  Any suggestions much appreciated.
