How do I make a coding sheet that's not in visual studios?

I am brand new to unity and learning how to code, currently following tutorials. My computer used to make a bank coding sheet if I kept clicking create script and ignoring the create a visual studios account, but now it's only letting e us visual studios. I can't research any words in visual studios like the Unity tutorials can in whatever they use. Additionally Visual Studios keeps trying to change the code that the tutorial sais to use and making it something else. Ian change it back so it's not a huge problem but it does get annoying.
