New Update:
Ok it seems that Office 2019 dose not include OneNote at all, according to below source:
OneNote 2016 gets less attention
Now we come to the feared bad news for many OneNote fans: Office 2019 will not include a new stand-alone desktop version of OneNote. It is replaced by the OneNote app for Windows 10 by default.
You can optionally install the previous version OneNote 2016 or continue to use it. But it will not receive any new features. (Incidentally, that’s been the case for a few years.) For at least two years, Microsoft still wants to provide security updates and bug fixes for OneNote 2016.
