The IRS will issue direct deposits to taxpayers that requested a direct deposit disbursement or applied for a new debit card when they prepared their own return online. An IRS-issued check will be mailed to taxpayers that requested a check printed from their tax professional's office, Walmart Direct2Cash or a Walmart MoneyCard issued by their tax professional.
If a payment is returned to the IRS (Ex. bank account is closed), the IRS will mail a check to the taxpayer.
This what I copied and pasted from Santa Barbara Bank who is actually the distributor of Green Dot. Since Turbo Tax wouldnt answer questions hopefully this helps.
