I need to know how much i earned in april 2020 ? and june 2020 ?

Nice to have you in the Community space, @lees-dirtydeeds.

You can run your Profit and Loss report for that specific month and see how much you earned for those months.  This report shows you your income and expenses. I’d be glad to guide you how:

1. Go to Reports menu in your QuickBooks Online (QBO) account:
2. Type in and enter Profit and Loss reports.
3. Adjust the date to the month to April year 2020 and click Run report (do the same for June). 

You can also personalise the report to the data you need to by clicking the Customise button.

It’s also a great practice to reconcile your accounts every month to ensure your account matches your bank statement.

If there’s anything else you need assistance with running reports in QuickBooks, let me know in your reply. I’m always here to listen and ready to help you. Take care and stay healthy.
