I'm wondering why turbo tax gave me a total of $3137 but when I received my federal it was only $1990

Did you owe any taxes, or child support?

Once TurboTax releases the tax return to the IRS, it is totally in their hands.

"The Department of Treasury's Bureau of the Fiscal Service (BFS) issues IRS tax refunds. 

Through the Treasury Offset Program (TOP) program, (BFS) may reduce your refund (overpayment) and offset it to pay:

• Past-due child support;
• Federal agency nontax debts;
• State income tax obligations; or
• Certain unemployment compensation debts owed to a state (generally, these are debts for
  • compensation paid due to fraud, or
  • contributions owing to a state fund that weren't paid)."
• Please see the original IRS article Reduced refund

You can check the status of your tax return.  You will need:

• Social Security Number.
• Tax return year.
• Hilling Status.
• Exact refund amount
