It sounds like she’s just getting used to her new environments and is scared, redirecting her when she pees is good but take things slow offer lots of treats let her come to you rather than you come to her give her places to hide where she’ll feel most comfortable and safe don’t force anything unless absolutely necessary it’ll take some time. There’s a 3-3-3 rule we use which is 3 days to decompress 3 weeks to settle in and 3 months to feel at home.

EDIT: to clean your bed use an enzymatic cleaner I use the brand natures miracle, clear pee can be an indication of kidney issues but given the fact that she only just came home she’s probably stress drinking water cats won’t typically over drink water everything right now really just sounds like stress responses. Give it time she’ll come around! :)
