First and foremost that depends on how you have credited the actress. Sometimes actors who acted as a reference for animation could be seen in "Cast" if they were credited there (eg. Snowy Winters in Evil Dead II) and sometimes that could be listed as "motion capture: character name" in "Visual Effects" (eg. Derek Mears in Middle-Earth: Shadow of War). Alternatively it could be placed in "Miscellaneous Crew" if the credit is unusual in both placing and formulation.
Hope that helps, but I might be able to tell you more precisely with more information available.
