Hello there, @mvp2885.
In QuickBooks Online, reporting will continue the balances from the last year.
However, if you wish to have zeroed out this year, you'll have to create journal entries. Let me guide you how.
- Go to the +New icon.
- Under Other, select Journal Entry.
- Enter the day of September as your Journal Date.
- Select the accounts and enter the amounts of your journal entry.
- Choose a Name.
- Click Save and close.
Once completed, you can now be able to enter the Journal date and record your journal entry successfully. I've also included our detailed guide in recording your journal entry.
Also, please refer to your accountant. They can provide further guidance in creating journal entries and ensuring your books.
Lastly, you can check out this helpful article for your future reference: How to Reverse or Delete a Journal Entry?
Please let me know if there's anything else I can do to be of assistance. Have a good one!
