you probably have a non O. Non oa requires a health check, a criminal record check and insurance. Non o has none of those requirements.
Visit your local immigration office (which you'll have to do anyway to get a residency certificate for the bank) and ask them for a handout for the requirements for the yearly extension. It varies a bit from office to office, so you need to get specific info.
And lastly, it's not reporting every 3 months, it's every 90 days.
But for now, just visit immi and ask for a residency cert and requirements for the yearly extension.
