State tax filing

Thanks.  This is where I get confused: 

Select Edit or Add to report the amount of income and taxes paid in Virginia for the California sale of property taxed in Virginia" 

I do not know how to figure how much taxes were paid in VA on just the sale of the property?  The full amount of my earnings plus the gain from the sale are transferred from my federal return to the VA state return, and the VA state return calculates the taxes owed.   I am not clear on how I would separate the taxes specific to the sale?  Maybe I am not seeing this clearly, and need to take a break?  Been at this most of the day!
