I only entered the T3 on my husband's return, saying that 50% was split with me. Boxes 49, 50 and 51 for dividends, and box 26 for other income were split properly. But box 21 for capital gains was not split. I think I know what happened. Because capital gains are now split between period 1 and period 2, additional boxes were added, boxes 52 and 53, with the capital gains split by period. These are the boxes that were used to calculate the gains on Schedule 3 instead of box 21. It seems that the 50% split was not picked up for these additional boxes 52 and 53.
