Have you encountered any specific error messages, such as error 102, 105, 390, or 1000 when trying to connect your Merrill Lynch account, Jen?
If so, I recommend following the troubleshooting steps outlined in these two articles:
While working through those steps, please check Merrill Lynch’s website or contact their support to confirm if any ongoing maintenance or service interruptions are affecting the bank connection.
As a temporary workaround, you can manually download your bank transactions from Merrill Lynch and upload them into QuickBooks.
If you have any additional questions, let us know.
