If she has received a Social Security number for work you will no longer need an ITIN. That is only used in the event you cannot get a Social Security Number. So I would just go ahead and either wait or send an amended return with the Social Security number for her on it with an explanation that she has now received her Social and no longer needs the ITIN. You can then also file the state taxes using that social. From now on that is what you will use. The Social Security number is for life.
