This is a lifesaver - thanks for posting. One additional comment based on my experience doing this for 2020 taxes: once you've deleted the temporary state return, TurboTax will zero out the credit claimed for taxes paid to the temporary return state on the Schedule OSC on your Virginia return (but will keep credits for any other state that you entered). So you then need to go back into the Virginia return and re-add the taxes paid to that state.
They don't make it easy...
