Tax confusion for online work (staying more than 183 days)

I have two income streams. Teaching English (which I just quit to do freelancing full time) and my freelancing work. When combined, the money I made is over 1 million NT. According to the tax office, I still didn’t need to claim the money I made freelancing.

I’m not sure if this is because the tax office doesn’t combine the two income streams or if freelancing work is treated differently.
