GST Nature Of Business And Return Filing

I am setting up an online training website cum business. Since it's online I was informed that I should register for GST. So I approached someone nearby and made the registration. When I was exploring through my GST portal I found that I am registered as service provider and other services. I have a few questions 1. I need to file as an e-commerce operator or a normal taxpayer. 2. Is my nature of the business right? or should I change it?
