Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund.

Is the amount sent/issued by the IRS the same as the refund amount shown on your federal tax return Form 1040 Line 35a? - https://www.irs.gov/refunds

What exactly is indicated on the IRS website for the tax refund?

If not, then go to this IRS website for information on reduced refunds - https://www.irs.gov/taxtopics/tc203

The IRS will be sending you a notice in the mail which will explain what the IRS changed on your tax return that resulted in a lower tax refund.  There will also be a procedure to use if you disagree with the IRS changes.

Are you also receiving a state tax refund? If so, the state refund is sent directly to you based on how you chose to receive the state tax refund.
