Ok so my mod is a combination of Tuning and Scripting mod. I tune the Buffs and BuffTooMuchSun And I also have a script in the package. It's a script Tuning combo. The question is should I upload it as Script Or Core Mod section or Override section or Miscellaneous section.
I'm uploading for the first time so please help.

I'm no expert but I would imagine as your mod contains scripting, it would be classed as a script mod and should therefore be uploaded as such. :-)

Thnx for replying but after reading and taking my options in and checking what other modders have done where my mod resonates more as a miscellaneous game mod in my opinion. Hope it won't cause problems. I kinda already made that decision before I even got a reply I seriously hope the upload goes nicely without problems.

I would try to make a thread for any uploading questions in the Creator Issues Forums . There we'll be able to help you out with any uploading questions
