more efficient formula using index and match for breakdown of values in one cell

I have a datasheet of puchase orders which are itemised according to taxes paid .

However when there are different purchase orders but same itemised number for taxes, It's a chore to do this manually as attached in yellow and in blue the manual breakdown and brown the expected results which should tally with the totals for each itemised taxes

The data goes up to 1000 rows !!!

Take note the taxes are on sheet 2 but for ease of understanding I have put it on same sheet and label it at end of data.

Can anyone help to have a more efficient formula in one cell for each taxes
