It depends on your filing situation. If you had no TurboTax fees or paid the fees by credit or debit card up front *and* you got a refund, the IRS should have your real direct deposit info and the stimulus should go there. However, if you had fees deducted from your refund, the IRS got direct deposit info for Santa Barbara TPG instead of your bank; what will happen there is uncertain. https://www.sbtpg.com/coronavirus-stimulus-payment-info/
If you owed the IRS money for both 2018 & 2019, they may not have your direct deposit info at all. However, the IRS plans on creating a special portal where taxpayers can provide direct deposit info and avoid paper check delays. https://www.irs.gov/newsroom/economic-impact-payments-what-you-need-to-know (This will also apply if SBTPG doesn't forward stimulus checks and the IRS sends them paper checks.)
