Looking at the Asset Entry Worksheet, there is a section called "MACRS Property Involved In A Like Kind Exchange or Involuntary Conversion."  I think I need to Elect OUT of Regs 1.168(i)-6T(i) by checking YES.  My eyes have glazed over reading the instructions and my brain just checked out.  Has anyone done this before because I'm totally lost on how to fill this out.

BTW, I just found out that the replacement asset was put in service before year-end - it just hasn't been totally paid for.  So I've done a journal entry on the books to accrue the balance due and set the replacement up as a fixed asset.
