Is the Canadian capital gains calculation (T3 slip) in TurboTax Premier 2024 correct? It should be box 21 - box 37, but I am getting box 21 + box 37.

Entered a single T3 with box 52 857.09, 53 998.03, 58 89.98 and 59 27.38 so box 21 is 1855.12 and box 37 is 117.36. Line 21 on schedule 3 should be 1737.76, but the software says 1972.48.
