Some states require that the old parts be *offered* (Ohio is/was one). Some states don't have a requirement at all (here - WI) and all states have different statutes. If CA has a requirement that it be "requested on the work order", you need to:
- Find out if it is a further requirement that *you* sign it (doubtful for precisely your situation) or if it merely need be noted by the service writer.
- Find out if it *was* noted (You *do* have *your* copy, don't you?).
Proceed from there.
