If you owed federal income taxes on your 2018 tax return, then the IRS does not have a direct deposit account for your name and Social Security number. The stimulus payment will be sent to you by the IRS as a check in the mail to the address entered on the 2018 tax return, if you are eligible for the stimulus payment.
