I'm here, Karol1. I'll help you check the list of transactions without attachments.

If you want to see the list of expense transactions that don't have attachments, you can follow these steps:

1. Click Expenses.
2. Go to the Expenses tab.
3. Click the Gear icon above the ACTION column.
4. Tick the Attachments box.

If there are no attachments, you can see the Attach a file link. You can also export the list by clicking the Export to Excel icon.

If you want to see the sales transactions, you can follow these steps:

1. Click Sales.
2. Go to the All Sales tab.
3. Click the Gear icon above the ACTION column.
4. Tick the Attachments box.

You can also export the list so you can have a better view of the sales transactions that don't have attachments. 

I'll also include this article to help you manage your attachments: Attachments in QuickBooks Online.
