The stimulus payment will go to the account you entered for direct deposit on the 2019 tax return. The direct deposit information cannot be changed. If the account is closed the IRS will send the payment by mail or on a debit card.

If you do not receive the second stimulus payment on or before January 15, 2021 and you are eligible it will be entered on your federal tax return, Form 1040 on Line 30.
The Form 1040 has not been finalized and needs to updated to include the 2nd Economic Impact Payment.
You need to know if:
1. You paid for your return before filing or
2. Did you have the fees taken from your refund or get the Green Dot debit card
If #1, the stimulus check will go to your bank account directly from the IRS.
If #2, the stimulus check will go to SBTPG/Green Dot and then be routed to you. My understanding is an additional 1-2 days. You may contact Green Dot at 888-285-4169.
You may check the status of your payment at IRS.gov/GetMyPayment.
