That means if your client, who needs to file a return but just hasn't yet, uses Turbo Tax Stimulus Registration, he/she may unwittingly be filing a nil return (see https://proconnect.intuit.com/community/proseries-discussions/discussion/re-direct-deposit-for-stimu...).  Intuit should be more transparent about what it is and is not.  If they can say that $1 is added here and there in the submission, why can't they say whether that amounts to filing a return (or not)?  Hope it is not but if it is, I see trouble brewing...

In case your client is due a refund on the 2019 return and it is e-filed now, the direct deposit will get to the IRS.  Otherwise, your client is probably better off waiting for the IRS to roll out its own portal for direct deposit submission.
