I have a client that went to the IRS website to enter direct deposit info for the stimulus because this couple always owes and the account info was not on file.   This was before they had filed her 2019 return.  Now that I have filed the return, it rejected and says social has already been used.  I'm familiar with the fraud aspect, but could it be that the stimulus site is causing rejects?  Any thoughts on this?  I understand that mailing is the only option now.  Thanks.
