You would enter the full amount of your expense (sales tax included) into the column that corresponds with the sales tax you paid for that expense. Ex: If you bought Supplies and you were charged HST on those supplies, then you would put the full total (price + HST) in the HST column.
It is asking about GST & HST taxable and zero rated/exempt because if you were eligible for the GST/HST rebate, these columns would help determine your rebate.
