If you're using TurboTax Desktop Premier, and the FILE > REMOVE STATE RETURN option does not remove Washington, have you tried selecting 'Mail my Washington return' and 'Efile' for your Federal return'?
You should be able to Efile your Federal return separately. See Filing Federal and State Returns Separately.
If these suggestions don't work, you may want to perform a Manual Update and re-try Efiling just your Federal return again.
Lastly, in FORMS mode, you could delete all the WA forms manually, or just the Working Family Tax Credit form, then try FILE > REMOVE STATE RETURN again.
Let us know if none of these options resolves your issue, and we'll try to help. You can also Contact TurboTax Support for more help.
