I do not know the exact reason that the IRS did not refund the amount that you were expecting to receive, but common reasons that could have resulted in your refund being different than you expected, is that you asked for TurboTax fees to be subtracted out of your federal refund, your refund was changed by the government to correct a calculation error, or to correct a discrepancy between information reported on your return and information reported to them from other sources, or through a refund offset. A refund offset is when an IRS refund is reduced or intercepted to pay off debt, such as past-due child support, outstanding student loans, or unpaid state income tax.
You will always receive a notice in the mail if an adjustment or offset occurs. The notice will include the original tax refund amount and the revised amount. It will also include the agency receiving the offset payment and that agency’s contact information. If you believe you do not owe the debt or you want to dispute the amount taken from your refund, you should contact the agency that received the offset amount.
If you have questions regarding the offset of your federal tax refund or offset of another U.S. government-issued payment, you can call the Treasury Offset Program (TOP) Call Center to obtain agency contact information during customer service hours.
