Hi there, info2389. You can edit your current financial year in QuickBooks Online (QBO) directly in the Account and settings section. 

To adjust your financial year settings, begin by navigating to the Gear icon > Account and settings > Advanced > Accounting. Select the dropdown menu for the First month of financial year ▼ and choose the month when you start your financial year. After that, click Save and then Done.

If you have any further questions, feel free to return to this thread.
