Has the IRS released your funds to SBTPG?  Check here:
http://www.irs.gov/Refunds

If it hasn't been released, you can phone the IRS and speak to a live agent to see if it is too late to stop it.  Depending on the stage it is in, they may be able to stop a refund at the IRS level and send a paper check to the address on the return, but they won't change any deposit information.

Or:

If there's still time, you could phone SBTPG and see if they can do anything.  They used to let people change account info there by logging into their SBTPG portal there.  But they may have quit doing that due to all the identity theft and fraud. It's possible they might be able to stop the deposit from SBTPG to your bank, however.  I don't know if they will do that.  And if they do, they might require you to submit ID verification.

If you want to talk to SBTPG, they have live support during the day.   Here is the contact page.  At the page below scroll down to see the Live Support number.

Here's how to log into your info at SBTPG.  Choose the taxpayer portal at:

IRS:  800-829-1040  hours 7 AM - 7 PM local time Mon-Fri

Listen to each menu before making the selection.
 
First choose your language. Press 1 for English.

    Then do not choose the first choice re: "Refund", or it will send you to an automated phone line.
    Instead, press 2 for "personal income tax".
    Then press 1 for "form, tax history, or payment".  
    Then press 3 "for all other questions."
    Then press 2 "for all other questions."  It should then transfer you to an agent, but there is likely to be a long wait.

I usually use a speakerphone so I can work on something else while waiting.

I put the wrong routing number for my taxes. Who do I speak to about this matter?

Once the tax return has been filed the method of receiving the tax refund cannot be changed.  If you entered the bank routing number incorrectly the direct deposit will be rejected and the refund sent back to the IRS.  The IRS will then mail a refund check to the address on the tax return.
