So I went into a rabbit hole here, and found this. Getting to know the Turbo® Visa® Debit Card
In it, it says "Turbo Tax works with Green Dot to get the IRS and/or the State your account information" so I am pretty sure that answers our question as to wether the IRS has our Turbo Tax Card account number, right? And that being said, since the IRS does have our account info, then that's where they would send the stimulus check.
