State tax filing

Thank you.  I am using the desktop version and, when I go to Forms view and look for this item, it appears to be Line 29 ("Conformity Subtraction") of Form 760PY.  TurboTax auto-populated an amount in that line under the "Income From Federal Return" column and is looking for me to populate the amount for that line item under the "Income While Virginia Resident" column. 

 

I don't see anywhere on that worksheet to do data sourcing on the amount in the "Income From Federal Return" column that TurboTax auto-populated that would enable me to determine what portion to allocate to VA in the "Income While Virginia Resident" column.
