How can I add the $2 per day business-use-of-home for 2020. I read in the CRA website that that was permitted for 2020 taxes

If you are using TurboTax Online free, please follow these steps:

1. In the sidebar on the left, choose Income

3. Read the given conditions, and if you meet them, click YES
4. Answer required questions to create your Employment Expenses Profile

Please make sure you answer "YES" when you see the question "Do you want to claim your work from home expenses?" on the bottom of your T4 Slip
