Your refund was processed by Santa Barbara Tax Products Group, regardless of the name on the check. Either they have your funds, or they sent the funds back to the IRS. If SBT has your funds, you can try calling them. However, they may simply send the funds back to the IRS as a safety precaution, because in the past they have been scammed by people claiming misdirected refunds.

Once the IRS has your funds returned from the third party banks, they should mail a check to your address of record, although that will take 4-6 weeks after they receive the funds. If it is longer than that, you can ask the IRS to trace the refund and issue a new check.

Turbotax simply will not have any information about your refund at this point. Turbotax can't access your account at the IRS, and banking privacy laws probably prevent Turbotax from directly accessing your information at SBT. You need to work with SBT or the IRS directly.
