Missing Funds

The IRS confirmed multiple times I would receive 9844.14. No off sets connected to my SS# at all! I checked multiple times. I only received 8814.44. I am missing over 1000 dollars and I need answers. I will never be using trubotax again! I called and the agents are poorly educated. They tell us to call the bank of TurboTax. You call the bank, they say call the IRS. I want my additional money owed to me.
