Scenario: The site is setup to offer the 8888, but the taxpayer only wants their refund deposited to one bank account.
Where should I enter the bank account information?
You should enter the information in the Bank Account 1 section and select the Pull Refund button.
DO NOT skip Bank Account 1 and enter it in either Bank Account 2 or Bank Account 3
This will result in a validation error because IRS MeF does not allow this scenario
Solution: Enter the information in Bank Account 1 and remove it from Bank Account 2 or Bank Account 3 and transmit the return again.
