Can anyone help me zero beginning balances that have rolled over from the previous year?

I'm here to assist you in editing your beginning balances in QuickBooks Online (QBO), @lesley27. 

QBO allows us to manage our beginning balances to keep accurate financial records.

Also, it's important to note that we have to be careful when editing our beginning balances in QBO as it may mess up our books and the previously reconciled data. With that, I recommend reaching out to your accountant to ensure you have accurate books. 

To edit our beginning balance, perform the steps: 

1. Go to Settings and choose Chart of accounts.
2. Locate the account and select View register.
3. Find the opening balance entry. 
4. Select the opening balance entry.
5. Edit the date, then the amount. If needed, select Edit to make your changes. 
6. Click Save.
