First, I would expect weight loss to slow as you get closer to your goal weight. 10lbs a month is not going to happen forever. Also, how realistic is your goal weight?
Second, at some point you need to ignore the scale and go by measurements, especially waistline.
Now as to macros, 20g carbs sounds great. Are you tracking your foods? And is that net or total? Some people respond better to limiting total carbs or eliminating specific foods like nuts or dairy for a while. The protein sounds a bit high to me, unless you are intentionally building muscle, but if you’re in ketosis then you’re probably good. The fat macro is not a goal. If you’re not hungry, eat less. If you’re tired or cold for no good reason, eat more.
