Customizr and W3totalcache

Hi,

I am using customtizr theme and using w3totalcache to speed up my site, I
read this article
https://docs.presscustomizr.com/article/178-how-to-setup-w3-total-cache-plugin-with-the-customizr-theme

Having some difficulties though for the setting, especially in the js and minify setting.
1.For the JS I just copy paste form the article, is it Ok?or do I need to check from customizr folder?
2.For the css file,
Where can I see the list of my stylesheet?
my website is https://twinmesinhoreca.com

You need to view your HTML source for your actual list of stylesheet URLs.

Which one should I use in the css setting?
Thank you
