I have had the same issue. Finally was told the account had a active and closed folder. I advised same client, same email address and same password. I  called support 4 times and requested escalation. I was told use another email address. Really. Tell the client sorry you have to get another email address as Intuit can't fix their link product. I was advised that Intuit support could not close the invalid folder and re open the original valid folder. What kind of customer service is that? Client did not do anything wrong, Intuit just didn't want to fix their link issue!!!! I had resent the email 5 times and even deleted the 2024 return and brought over another. Very Poor service!!!!!
