How to update / change the amount of Retained Earnings Equity in Quickbooks? please schedule the online chatting with me by return. Thanks.

It's nice to see you here,userbanff. 

 I have a few insights into how to handle retained earnings in QuickBooks Online.

You can enter an opening balance into your retained earnings account by creating a journal entry.

Here's how:

1. Select the (+) New icon.
2. Choose Journal Entry.
3. Arrange the date for the opening balance to match.
4. On the first line, from the Account column, select Retained Earnings.
5. Fill in the amount of the balance in the Credits column.
6. On the second line, select the account we're using to create the balance.
7. Enter the amount in the Debits column.
8. Click Save and close.

I'd also recommend consulting your accountant to make sure you're recording your expenses accordingly.
