You'd use Sch D but you'll need to adjust (decrease) the basis by the deprecation that was taken back when it was a rental.  If you end up with a loss, it wont be deductible since it a second home.

I "think" if you use the Homesale worksheet and answer the questions (and use the adjustment to basis worksheet to enter the depreciation) it will limit the personal loss automatically, if you use Sch D you have to limit it manually.
