I have three children that are all dependent, butI only received $73 dollars for the child tax credit? Did I mess up or did turbotax and how can i fix this?

I've been using Turbo for 7 years and have never had a problem. I entered and re-entered eveything a dozen times and it still came out to $73 dollars for three dependent children. If I'm not mistaken, its supposed to be 2000 a child?
