I appreciate you reaching out to us here, with regards to your TD bank connection with QuickBooks Online. This has been reported by other customers, so you are not alone. It's been escalated for further investigation with our Development Team. However, I don't have an ETA for resolution at this time. I recommend contacting our Customer Care team outside of Community, so they can add you to the list of affected users, and ensure you receive an email notification when the issue has been resolved. In the interim, you can manually upload your transactions by following the steps here.
