One possibility is that you selected the optional Refund Processing Service to pay your TurboTax Online fees. If you did, your TurboTax fee plus the additional processing fee is deducted from your federal tax refund.
Another possibility is that your refund was reduced by the IRS, either to correct a calculation error or through a refund offset. You' will receive a letter from the IRS f your refund amount is different from what was on your return.
Please keep track of your refund at the Where's My Refund? https://www.irs.gov/refunds page on the IRS website.
Please let us know if this helps.
