Quick books hasn't been able to link with my bank account in months. Contacted my bank and this isn't an issue on their end

Let's resolve the error you're having to connect your bank account successfully, @userrachellesslie.

Can you tell us more about the bank that you're trying to connect to and the error you're encountering? That'll help us get the best resolution for the error you're having.

You can check this article for more information about bank errors that you may encounter and steps on how to fix them: Enhanced Standard Feed Connection Errors.

In the meantime, you can manually download the transactions from the bank and then upload the file to your account. Check this article for more information: Manually upload transactions into QuickBooks Online. 

From here, you can now categorise and then reconcile the transactions.

Let me know if there’s anything else that I can assist with about your bank account by leaving a comment below. I’m always here to assist. Have a wonderful day!
