This might entirely be a temporary fraud protection for your benefit that it will not accept any change in banking information. I cannot begin to tell you the amount of fraud that has occurred this past year. I am a CPA and when not doing tax expert work I work for public companies in their fraud department. It is everywhere. Just sit tight until after the 12th and if it still is not allowing you to change bank information, then please let me know and I will see what I can do on my end.
