The IRS will send you a letter explaining the adjustment, but it usually takes about three weeks to arrive. If you got your refund already, check the IRS Where’s my refund? site to see what they adjusted and how it impacted your refund. It may take several days for the site to be updated.
For more information, please see the TurboTax FAQ below:
Why is my refund direct-deposit or check lower than the amount in TurboTax?
