Hello there, latifadam.
When encountering a bank error, the first step is to identify the specific error and work towards resolving it.
Can you confirm the exact wording of the bank error you've received? Any additional information will help me offer an accurate solution.
In the meantime, you can check this article for ways to help you fix bank errors in QuickBooks Online: What to do if you get a bank error or can't download transactions in QuickBooks Online.
Once fixed, you can match and categorise your transactions so they are accounted for properly.
On the other hand, QBO provides various reports, such as Profit and Loss, Sales by Customer, and Sales by Product/Service, which can give you a clear overview of your earnings and income over a specific period.
Keep me posted if you have any other banking concerns. I'm always here to help.
