When do I need to report my 90-day status after extending my Non-O visa for 1 year?

After extending your Non-O visa for 1 year, the date for your next 90-day report will be 90 days from the date you received your extension if this is your first extension. If it is not your first extension, it depends on whether a new 90-day report slip was given to you at the time of the extension. If a new slip was provided, the next report date is stated on that slip; otherwise, it is 90 days from your previous report. It's important to check your passport for the specific date. If you missed the reporting date, you can inquire about paying a fine at the airport upon departure, but it's recommended to check with immigration to understand the implications.
