You seem unsure of how your federal return was prepared, and it sounds as if someone else prepared it for you, which means you did not prepare it using your own TurboTax account. The information flows from the federal return to the state return in TurboTax software. If you cannot use the same account that was used to prepare your federal return to do a state return, then you need to figure out an alternate way to prepare your CA return. You cannot prepare a "stand alone" state return using TT. You could get the forms from the state web site and prepare them by hand, or get them done by a local tax preparer. You will need a copy of your federal return for 2018 either way.
