While I don't use Lacerte, I do frequently use negative numbers in a detail list for a whole host of reasons (many of which are already mentioned here).  It's very convenient to have those details in the tax return software.  If this were tax filing software provided by the IRS for free, sure, suck it up and deal with it.  But you folks pay thousands of dollars for a product that should make your life easier, not more difficult.

Sounds like Intuit has come up with a Lacerte dehancement.  They've been dehancing ProSeries for years.
