She can apply for ILR with you , provided she is still dependent on you and have not formed an independent life of her own.
Your daughter can apply for ILR from within the UK or outside ,
However, if she applies from abroad then she would have to wait till the decision is made on her application, to return back to the UK.
Usually you can apply from your home country and country of your residence.
My pleasure. Have a good day. Best wishes.
