No. You will not have an DC state income
tax filing (due to the reciprocal agreement between DC and VA). Just select
"no" to " Did you make money in any other states?" under
the Personal Information section in TurboTax (see screenshots)
You can get rid of a
state without clearing your federal return by just deleting the state from your
list of states under the "State Taxes" tab.
Please note that you
will not have a delete option until you actually start working on the state.
Select that you want to start the state return under the state taxes tab. The
system will start calculating. Then go back into the state tab at the top of the
screen and you should now get a choice for that state to either continue or
delete. You won't be charged for just starting the state return. You would only
be charged (if applicable) when you are getting ready to file.
