After you file

Actually his very 1st tax return was e-filed then his 2nd.   So they accepted the 1st two.  I have used Turbo Tax for years before that and never received a no.  That's why I think for signatures you should have an option to use the pin or "sign" it on the form then e-file it.  But you can't do it for state either on California's website either so I have to deal with the pain of mailing it.
