Hello, I have a series of formulas I need to complete with the data from the second tab, but I have no idea where to plug in which numbers?

I also have to create detailed summary, which I can do, but I am struggling with identifying where the numbers go in the grey area of my spreadsheet.

Could you help me fill in the highlighted Yellow columns for Valero 2020 and 2019? I can then decipher how to complete the other fields. Thank you so much.
