State tax filing

This still isn't working for me.  I'm on desktop, Premier edition.  State ID seems to be set to MX. But I cannot change it to XX.  I've already in smart check entered the individual (4 states including one twice as I moved so part year and part resident and part not resident). This may be where the software blocks me.  In any case the field does not seem to be editable.  I select it, icon comes up, but the field does not change.
