TDEE-%20 questions for 5ft 5in women

Hi!
I have been wondering if my calories are too low. So I read on here to find a TDEE calculator, enter my info and then deduct %20. I am 5ft 5inches, 29 years old, & 160lbs. I do 40minutes of cardio in the morning and 35 minutes of weights in the evening. I work at a desk job 9 hours a day.

I entered my information on this site http://iifym.com/tdee-calculator/
It told me that my TDEE is 2322 calories per day.
If I calculated right, to deduct %20 from that would be appx 1850 calories a day to lose weight, without eating back my workout calories (since I put my workouts into the TDEE calculator).

1850 seems way to high for me to lose weight. I was anticipating close to 1500.

Are there any women out there with similar stats that lose weight on a diet of 1800-1900 daily calorie intake?
