This was originally blank, should I just leave it blank?
Where are you reporting the sale? In the SCH E section in "sale of assets/depreciation"? Or in Sale of Business Property? If in SCH E section, something's not right. If in "Sale of Business Property" enter the original acquisition/purchase date.
Also, do I need to enter Nonrecaptured section 1231 losses?
Only if you're reporting the sale in the "Sale of Business Property" section. If reporting in the SCH E section, you shouldn't even be asked for that, as the program "knows" what to recapture in that section already.
