T2202 is a required form, provided by your employer, to claim employment expenses. If you are an employee receiving a T4, you must declare these expenses in the Employment Expenses section.
If both of you have a T2202, each of you must claim employment expenses on your respective return.
In TurboTax Online, you will have to do it under Employment expenses (in Income section) and in TurboTax Desktop, you have to fil out a T777.
Thank you for choosing TurboTax.
