Can't efile in Washington state

We do not have state income tax in Washington state but Turbotax will not allow me to skip the state income tax portion of the filing like it has in past years. This year it requires me to answer questions and then tells me in am not able to efile because of my answer to the questions. I've always been able to file my federal returns electronically and not file state. Now I'm stuck in a loop and I'm unable to print the federal for mail in and its not allowing efile. What's going on? Can anyone advise?
