You are correct that your management report ends in February instead of March 1, Ant.

To fix the correct management report, here's how you can do it:

1. Click the Settings () icon in your QuickBooks Online dashboard.
2. Go to Account and Settings and select the Advanced tab.
3. Scroll down to the Accounting section, and ensure that your fiscal year start month is set to March.

Here's how:

1. In the management report page, locate the specific report you’re working on.
2. Under the Report Period column, select the This Financial Year option.
3. Click Preview to ensure the report now reflects the correct period ending in February.
