last year i was able to see the amount of my tax return as i adjusted or filled out my information. so why isnt it showing me that until i complete everything?

usually in the upper left hand corner, it will show you the amount when you type in your W2's, then the number will usually go up if you add dependents. and so on..so my question is, why is it not showing me these numbers as im doing my taxes like it normal does?
