TurboTax is indicating that I owe ±$2,400 to DC, despite having income withheld throughout the time I lived in DC. When I follow the instructions for the D-40 EZ (working quickly to get a ballpark number, using standard deductions, etc.) I seem to find that my tax burden is also landing around ±$2,400. Over $3,000 of my income was already withheld according to my W-2s, so why does TurboTax indicate I owe additional tax to DC? Is it neglecting to account for the withholding on my W-2?
In 2017, I lived in DC from Jan-June, then Virginia from June-Dec. The only thing I can think might make a difference is if my DC income is still taxed at the higher bracket based on my full annual income rather than the income I received while living in DC.
