how do I enter security option deduction at Turbotax as I sold CCPC shares that I exercised option earlier and don't get T4. I only report taxable gain when I sell shares

[martino-one]

I exercised canadian controlled private company options and held shares in 2023. In 2024, I sold shares, so I need to report taxable gain. in the turboxtax, I report line10400 for other employment income, but I can't find security option deduction I can enter at TurboTax as this line is only available at T4, which company didn't provide as I held shares from exercising options. Basically, I would like to claim 50% for security option deduction, but don't know where I can enter at TurboTax. I tried at other deduction page, but there is no security option deduction there.
