Inaccurate federal tax return deposit via TPG

 

On 8 Feb 18, I received a direct deposit via TPG for my federal tax return.  However, it was not the amount I was expecting to receive.  Per the IRS, my federal return deposit should have been $1990.14, but all that was deposited was $100.83.  Even with the TurboTax filing feeds, that is still far less than what should have been deposited.  Please advise.
