After you file

the DD info on your return does indeed match your card and if you use direct deposit for your paycheck you will see it matches. The IRS has the information from your tax forms so I would assume that this is the banking number it will get. The other agreement is allowing the third party bank to act on your behalf BEFORE the direct deposit is done however at this point that agreement does not exist the IRS will get its info from your tax filling aka your form info
