State tax filing

Thanks.  It is accurate.  I had a situation where I moved, and my boss didn't change my work location.  Withholding kept going to CA which was OK since we moved out of state, and we were selling a house.  I knew I would be needing the funds with CA.  However, I'm now in this pickle.  Is my only choice to MAIL the forms?  I don't see why this would be a reason to not be able to efile.
