One clarification: If a TurboTax customer chose to have their tax return software fees paid out of their refund, the IRS was given information that sent the refund to a third party bank. TurboTax sends information to that bank so they know what to do with the refund when they get it. That bank, after receiving the refund from the IRS, pulls out the TurboTax fee, pulls out their own fee ($40), and then send the rest to whatever method the customer set up for their refund. If the customer uses a prepaid card or a regular bank account, there is a routing number and account number for the deposit of funds.
Since the IRS would only have the third party bank, there is no way for the IRS to know about your own bank account or prepaid card number.
According to Santa Barbara TPG, a Green Dot Company:
"The IRS will issue direct deposits to taxpayers that received a direct deposit. An IRS-issued check will be mailed to taxpayers that received a check printed from their tax professional's office or a debit card issued through Santa Barbara TPG."

As a professional tax preparer for over 35 years, I interpret this to say that, if the SBTBG was involved in getting your refund and forwarding it to you (either by direct deposit or Green Dot card), you can expect to get a paper check. I believe that if the IRS has your Green Dot (or any other prepaid card) routing number and account number, you should expect the stimulus check to be deposited in that account.
The key here is knowing how you got your refund. Did it come from the third party bank, or possibly the preparer who gave you an advance and then collected the refund when it arrived, or did it come straight from the IRS to your account?
