Moved last year from DC to VA (less than 183 days in DC). TurboTax is calculating VA properly, but is not prorating DC taxes but using full-year income. How do fix this?

TurboTax in calculating DC taxes is using my yearly income.  I've changed my dates of residence in both the personal info and state info sections, but no matter what I do, TT continues to use my full-year income to calculate the DC taxes.  My other state taxes for Virginia is being calculated properly, with correct prorating.
