I owed the IRS and paid via a credit card, not through bank. If they are using 2020 banking info, how will the stimulus money be deposited if this isn't my regular bank account? The first and second ones I received without any issue, but the banking info was direct deposit then.
The IRS should use the bank information from 2019 for the direct deposit of the third stimulus payment.
