I have the exact same problem this year. I have my property number entered but it's asking for an adjoining lot which I don't have. I think it is a glitch in the system because my old house from 2 years ago had an adjoining lot and seems like somehow it is remembering this and trying to force it on me even though I no longer own that property. Very frustrating as it won't let me file with the box blank, I'm going to have to type "Empy" in the box and hope for the best.
