Asset entry worksheet.

As Lisa said, the actual sales information can be entered on the Asset Entry Worksheet.  But you are also supposed to enter the informational amount on line 1a of page one of the 4797.

Asset entry worksheet.  I always enter the EIN and name of abstract on the supporting statement

I think you have to enter the information in the Asset Worksheet. Do not forget the depreciation recapture. Also do not forget the IRS requires you report the sales of the land and the sale of the building separate. The sales of the land will go to part I Form 4797 and the sale of the building should go to Part III, If I remember correctly. Good luck.
