ANSWER:

If she did not stay with him behind closed doors at all, there is no iddah on her. 

Sheikh I would like to know about iddah after khula. My friend was forced to marry her cousin when she went abroad to meet her family. Only the nikkah took place no Walima etc. After the nikkah she stayed at her mother’s house and did not spend any time at all with her husband or consummate. Does my friend need to do iddah once she gets khula?
