How do I file union dues if they aren't appeared in box 44 of T4?

If you are using TurboTax Online, search for “Union or Professional Dues” on the Tax Home page. 

 

If you are using TurboTax Desktop in EasyStep mode, select Deductions & Credits > Payments Profile from the left side menu. Then check off “Union, professional or like dues not reported on a T-Slip” on the “Your payments profile for 2024” page. Then continue forward to the “Union or professional membership fees” page where you can enter your amounts.

 

If you are using TurboTax Desktop in Forms mode, search for “Union Dues” receipt page.
