Got asked if we had paid property taxes on our (primary?) residence in another county. We own only one residence. How do I remove that?

Our information appeared to transfer from federal to state okay, although it seemed odd when it asked to confirm our address by typing it in at one place.  Eventually it asked how much we had paid in property tax on our residence in another county, but no such place exists.  I can't figure out how it pulled that out of thin air or how to correct it.  When I try to go back to "state," it keeps asking me if I want to add another.  No!
