If I received a cheque from my employer for a bonus. It is not included on my T4. Where do I add it in Turbotax

Not everyone will have a Box 40 amount on their T4 slip. However, if you do have an amount for Box 40, that same amount is also included in Box 14—Total Employment Income. T4 Box 40 | 2024 TurboTax® Canada Tips - Intuit

If they are not included on your T4 slip, report them on line 10400 of your return.

Thank you for choosing TurboTax.
