State tax filing

So I definitely didn't enter anything wrong. Maybe turbo tax is miscalculating. Upon answering turbo taxe's questions in the order I was asked, I watched my federal refund drop by $2,799 after submitting my 1099-G form ($9,171 no tax withheld) . I filed Head of Household with 3 dependents- 1 of which is a child and my total income for the fiscal year was 36k (UEB included). The total amount of federal tax withheld from my wages on my W2 was $2,131 although the total amount of tax withheld was $5,278.74 (Not FIT). I also entered a dependent care expense amount of $2500. My federal refund total now sits at $9,145. I guess my question now is if TurboTax miscalculated, do I start over and enter the info in a different order?
