I originally selected that my book was not distributed in Creative Space, as it had not yet been published. I am trying to sign up with KDP, but it's asking me to go back and select redistribution option. I can't find where I need to do that and until I do, it won't allow me to upload my content. Any ideas?
I don't know what you mean by "redistribution option." Copy and paste exactly what you are being asked for.
Let's step back for a moment and make sure we're clear on what you're doing. Did you start to publish a print book through CreateSpace? (not Creative Space). What are you trying to do now through KDP, print or ebook? You can do an ebook through KDP without any reference to what you may or may not have done at CreateSpace. And note that you should never ask CreateSpace to make a KDP ebook for you, because it usually comes out badly.
If you want a print book, CreateSpace is the place for you. KDP-print is buggy.
