Entering a County of Residence in Virginia for a deceased person.

I am filing for a taxpayer who died in 2023.  TT is forcing me to make a selection for "County of Residence" for 01/01/2024.   He was not alive on 01/01/2024, therefore not a resident of any county.  TT does not let me continue with the Virginia state taxes unless I select a County.  How do I get past this?  I have already listed my address as the mailing address, but I am in a different county than the taxpayer was in 2023.
