From your post it seems you are working in a desktop product and in "Forms Mode." On the VA Info Worksheet in Part II, in the Part-year resident area, in your (taxpayer column), assuming you lived in VA, all year enter 1/1/2023 in the date moved in box and either no entry or VA in the state box.
In your spouse's column verify/enter the September move date, and select Foreign (FC) from the dropdown.
On the 760PY INC for 2a select Thailand (TH) and for 1a assuming you lived in VA all year select Virginia (VA).
