If your return is still in review, you will not receive a notice and/or refund until the review is completed.
Once completed, your status will change on WMR and if the refund is taken for an offset, you will receive a notice.

NOTE: You can also contact the IRS Treasury Offset Program Call Center at 1-800-304-3107 to
ask if they have an offset for you on file. TurboTax would not have that
information.
