Hello there, @Viv11. I'm here to share some information about changing the description of your bank transaction in QuickBooks Online (QBO).

I understand the importance of editing the description of your bank transaction. However, this option is unavailable. For that reason, QBO will depend on the transaction shared from your bank to QuickBooks.

If you want to change the description, we can exclude the transaction and manually upload it using a CSV file and do the changes. Here's how:

Here's how to exclude :
 

1. Go to Banking.
2. Select the For Review tab
3. Choose a Transactionss
4. Select the checkbox of the transaction(s) to exclude.
5. Click Exclude.
    

Here's how to manually upload your file:

1. Go to Transaction, then select the Banking transactions.
2. Click the drop-down arrow beside the Link account.
3. Choose Upload from file.
4. Browse for the file you've downloaded, then click Next.
5. Follow the prompts to map and import your file successfully.

After importing the missing transactions, you can start categorising and matching them.

Additionally, if you're ready, you can reconcile your bank to ensure your books are accurate and all accounted for. If you need help with the process, you can visit this article: Reconcile an account in QuickBooks Online.

You can always get back to me here if you have any other questions about your bank transaction. I'll be around to lend a hand. Keep safe!
