Again, she’s not spayed and still pretty young. She won’t really take to litter training too well until she’s been spayed. But in the meantime you can keep her hay and food dishes next to her litter box because most bunnies eat and poop at the same time. You can also try to keep her water near there too. Continue what you are doing with the wiping up of the pee and putting it in her box, and scooping the poops and putting them in her box. If you notice she’s about to pee outside the box, you can gently nudge her towards it. If you notice she pees in one corner (most bunnies find one corner and pick that) you can keep the box there. For some bunnies it may be necessary to have two boxes. But for the most part, it won’t get a whole ton better for a little bit. Honestly, like everything else with bunnies, litter training is all about patience. Some bunnies just take longer than others.
