Thank you for the response, @Louis Humphreys. 

Yes, QuickBooks Self-Employed (QBSE) supports that bank. Importing your transactions serves as a workaround if you have missing transactions in QBSE.

Since it’s the account that is missing from your QBSE, I suggest reaching out directly to our Customer Support. They have the tools to recover those account to pull up new transactions.

Here’s more information on how to contact QuickBooks Self-Employed Support.

Let me know if there's anything else that I can help you with. Have a wonderful day!
