All of my accounts are updating except my main chequing account - it hasn't updated for a week. Is there something I can do to make this happen other than manual entries?

Hi there, 

It's vital your account Checquing account is updating and I'll be glad to share some info that can help get you back on track. 

Before we start, I recommend you to log in to your bank's website to confirm if the new transactions are posted in your bank account since the transactions downloaded to QBO are dependent on the data from your bank. 

After doing this, you'll need to manually update your bank account to bring in the transactions to QBO. Here's how: 

1.     On the left navigation bar, click Banking.
2.     Go to Banking tab.
3.     Click Update.

For your reference, you can check this article: How to manually update bank accounts.

If in case there are missing transactions in QBO, we'll need to download bank transactions manually from your bank's website and import them into QuickBooks using WebConnect.

If you need further assistance with the steps, you can contact our QuickBooks Online Support Team. They have additional tools to pull up your account in a secure environment and do a remote session. Let me know if you have other questions. I'm here to help steer you in the right direction.
