What does Ref # 2050607 say? I doubt it has anything to do with trying to force the wizard on you. My guess is that it is sorta asking you to verify that it is an exchange of real property. If it is, just ignore this warning and go on.
I've never been able to get the wizard to work.
I come up with the correct amounts (using a snifty, 30+ year old worksheet I have..) and then force/override the amounts on the F 8824 to match.
@sjrcpa does the same thing 🙂

I use TaxTools to create the worksheets (probably same as your spreadsheet) and from them I have had good success with the wizard. The wizard is NOT REQUIRED. I would still like to know what the diagnostic said.
