Opting out of e-filing CA return

We live in CA.  TT keeps telling us there is an error on our CA return.  There isn't so there's no way to correct it.  We want to opt out of e-filing our state return, but TT appears not to allow that, instead insisting it will deduct the CA e-filing fee from our refund.  NO!  Why are we being forced to pay to e-file a CA return that may be rejected?  Please help.
