My T5008 shows reinvested dividends-drips so do I still need to enter it if that div$ already reported w/ T5? No cap gain/loss-only reinvestment. Box 21&22 are blank.

No Box 19 either but shows $ amt reinvested to buy more shares. This $ amt is less than the total dividend $ rec'd & declared on T5. If I still have to enter T5008, do I just leave Box 20&21 blank?
