Thank you very much for your reply. The status is finally updated, but now it is "accepted with errors". I searched the error code in FBAR reporting requirements and corrected it in the form. I have ticked the "Amended" box in Form 114 and entered the BSA confirmation ID. However, PTO doesn't allow me to file and shows the following message:

"The amended return cannot be accepted while the status of the original filing is unknown. Please wait to file your amended return until the original return status has been returned. Problem occurred transmitting efile data"

I have tried eveyrthing. What am I doing wrong?
