According to one site, this may be why some are seeing the stimulus payment, and then it disappears. It's one possibility anyway, since Turbotax was pretty much telling us it should go on our cards. See below:
"Important information regarding Economic Impact Payments (EIP):
The IRS will be issuing Economic Impact payments directly to individuals and not to temporary accounts for bank products.
If the IRS inadvertently sent your EIP payment to the temporary bank account at Refund Advantage, this payment has been returned to the IRS to be distributed directly to you.
Neither your tax preparer nor RA have access to this payment or any information regarding it. Neither your tax preparer nor RA can update your disbursement information.
All questions regarding your EIP need to be directed to the IRS."
