Whom does the refund come from?

A federal refund will come from the IRS US Treasury and a state refund will come directly from your state.  If you are having the Turbo Tax fees deducted from your federal refund it will come from the 3rd party bank that takes the fees out.  The sbptg bank.  Did you get a deposit from them?   There is also a Extra $40 Refund Processing Service charge (45 in California) to have the fees deducted.  Are you still waiting for your refund?  Turbo Tax gives everyone an estimated date of 21 days.  It is not a guarantee.  Only the IRS can tell you when it will come.

IRS Where's my refund

My federal refund from the IRS showed up in my checking account as

ACH-A-xxxxxx IRS TREAS 310 (TAX REF)

Or it might say something like TAX PRODUCTS PE4 if you were having the fees deducted from your refund.
