Lower federal refund

Turbo tax told me I was getting a certain amount when I filed, its $2,000 less than what Turbo Tax said I was getting. Suppose to be "accurate" I paid over $100 to file using turbo tax this year and now im getting $2,000 less than what they said? NO it's not an offset, I already checked. Is turbo tax gonna give me a refund since they were no correct on the amount I am receiving?
