How are you entering the sale of this rental building? Through Depreciation or directly into the Dispositions screen? 

I think your question really has to do with the word "recapture". Think of it as depreciation is a loan. When you sell you have to repay it. Recapture is regarding "extra" depreciation beyond straight line. It will not show up on Schedule D, page 2, line 19 because that is where you put UNrecaptured depreciation. Look at 4797, page 2, line 26 - "If straight line depreciation was used, enter -0-" (which just shows as a blank, in Lacerte).
