I told her that dad wanted me to give her the keys which I have to go back and take from the store where I had forgotten them.
If it doesn’t make sense, that’s what I am trying to tell you about:
Dad wanted me to give her the keys. I went to the place where she lives to give her the keys. But then I realized that I had forgotten to bring the keys with me. I forgot to take them from the store where Dad gave me. So I told her I’ll go back to the store and get them back for her.
