Or did you mean that you have already received or will be getting a check instead of a direct deposit?
Is this your situation?
In 2018 did you have any TurboTax fees that you chose to pay out of your Federal refund? If so, the IRS would have first sent your 2018 refund to a temporary intermediary bank account where the fees are subtracted. So the deposit info the IRS would have would be for that temporary bank account. Since that temporary intermediary bank account used in 2018 is now closed, if they tried to send you a stimulus deposit, it would bounce back to the IRS who would issue you a check in the mail. If you did not pay any TurboTax fees by that method in 2018, then this paragraph will not apply to you.
