Still haven’t received my refund. And it said it was due on the 26th of February. The irs released it on the 15.

There is never a tracking number for a tax refund.   If the IRS refund site says the refund was issued on Feb. 15, then ..... did you choose to have your TurboTax fees deducted from your federal refund?  If so you need to see what is happening with the third party bank that receives your refund first.

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
