In both cases, enter zero.

Thank you. I have entered 0, however, my state, WA, isn't even on the drop down menu associated with this field. That's why I am stuck. The program is forcing me to fill out the state here. I haven't made money in any state other than WA.

Washington does not have any state income taxes for individuals and as such, there are no filing requirements there.  

Therefore, if you lived and worked in Washington for the entire year, you will only have to file a federal income tax return.
