I've found it's easiest to use the dispositions screen (screen 17). 

In Screen 17, make sure to enter depreciation allowed in the FORM 4797 section, and check the 'sale of home', '2 year use test met' and 'business use in year of sale' in the SALE OF HOME section.

Make sure to put the sale date (no sale price) into the depreciation screen (Screen 22) to halt depreciation.
