The peeing could be a reaction to being upset by the displacement (taking her somewhere she didn’t want to be), and it could also be from just general marking (placed someplace new; make it smell like her so she feels more safe). Until she’s spayed, this behavior probably won’t go away. You can potentially mitigate it by placing fabrics that already smell like her on those areas so she doesn’t pee there as often. Since this is a result of a new environment and potential hormones, the behavior will naturally subside as she becomes more familiar with everything.
There’s a possibility she’ll learn that peeing on those surfaces is okay, so the key is demonstrating it’s not okay each time she does it. Shooing her or promptly taking her away to her litterbox is a good way to make sure that association is made.
There’s only one place in my home where Wick is blocked off from, and he pees at the barrier wall daily. We’re never there to catch it, so he’s learned it’s okay to pee there occasionally. But for high traffic places like the couch or a main living room area, the habit to pee somewhere is less likely to stick because you can be there to dissuade her from making the connection.
