After you file

If the IRS sent a refund with "cents" included then it must be related to interest added for some reason.   But no one at TurboTax will know what the IRS did or why.   TurboTax gets no information from the IRS after you file your return.   The IRS will send a letter of explanation.   If you want to  call the IRS and sit on hold for a long time over a few dollars and change you can try doing that.   Only the IRS can explain the refund amount.

To call the IRS:IRS:  800-829-1040  hours 7 AM - 7 PM local time Mon-Fri
