State tax filing

Although it says in the Forms Availability for California, that Form 568 cannot be e-filed, it does seem as if yours was e-filed.   If you look on Form 568, p 1-2, at the bottom, there is a notice.  If the box is checked, you have to mail the form, as it can't be e-filed.   But if that box is not checked, it appears the form can and was e-filed with the rest of your return.  As long as your Form 568 does not include one of those exceptions, it can be e-filed.     @cherry12345
