I noticed the tax refund is about $150 higher if I put “No” for the question “If you claim employment exp for this T4?”. Is this No contradictory to the claim of WFH exp?

According to the Canada Revenue Agency (CRA), part of the eligibility criteria for the Work From Home office expenses for employees deductions can be claimed but cannot be claimed in tandem with employment expenses incurred throughout the year. The question that TurboTax asks you is contradictory to the Work From Home expenses as it is attempting to claim employment expenses incurred.

For more information, check out: Canada Revenue Agency (CRA) - Work From Home Eligibility

Also, Canada Revenue Agency - Line 22900 Employment Expenses

Thank you for choosing TurboTax.
