Phone agents have little or no knowledge of how the Modernized e-File (Mef) system works. Only the technical persons that maintain it would know how tax returns are actually retrieved.
States can get tax returns two ways. 1) The IRS can retrieve (poll) for both the Federal and State return and then the IRS does send the state return to the state.
2) Some states have installed their own system and do not use the IRS to get the return so they retrieve it themselves.
I do not know which CA uses. If #1 then the of the IRA has accepted the Federal return, the IRS will also have the state. If the State does not have it then the issue is between the state and the IRS.
Much of this is described in Pub 4164
