Showing Sheet Summary Data in Another Sheet?

I am building SheetB to compare my budget by categories (data entered manually for now) against my actual expenses (entered in SheetA - totals for each category are part of my Sheet Summary data). Is there a way to reference those Sheet Summary totals in SheetB?

Ideally, I will then be able to use SheetB to create charts in an expenses dashboard to track where I am in each category. Appreciate any insight from this group!
