Not sure what you mean by an "adjusted refund." If you amended your return by mailing a Form 1040X then the IRS mails a check to YOU.
If you are referring to the refund from your original tax return:
Your tax refund was not sent to TurboTax. TurboTax does not handle your refund at all.
Santa Barbara Tax Products Group, LLC (SBTPG) is the bank that handles the Refund Processing Service when you choose to have your TurboTax fees deducted from your refund. This option also has an additional charge from the bank that processes the transaction.
You can contact them SBTPG, toll-free, at 1-877-908-7228 or go to their secure website www.sbtpg.com
There are no circumstances under which your refund is ever sent to TurboTax.
