CA State E-Filing for RDP

TurboTax has been compatible with RDP for years now. Why is it so difficult to e-file my state? I have already e-filed both of our individual Federal taxes, and TT asks in the beginning if this is the MOCK fed to create the joint state. If you are asking this, why can't you just ask if we have already filed our fed with the IRS so we can e-file our state? There is no logical reason not to allow us to e-file our state if we have already filed our individual fed. Seriously TT, get your stuff together.
