So I already paid $5 but if I wanted to pay 5 more for the walkthough do I need to pay the 10 or can I just do 5 more?

When you look at payment options for it, does it ask you for another $10 or does it say just $5 to unlock it?
My suggestion if it requires another $10 would be to get a refund (via Itch support support@itch.io) on your $5 version and then pay for the $10 version. I think they'll be willing if you explain your plan to them.
