Error: Employment expenses - COVID-19

Hi. 

I got the below message that's preventing me from filing my taxes. I tried to fix it, but I guess I don't know how to do it. Where did I select to transfer income to the form for working from home due to COVID-19? Any advice? Thank you.

 

You've completed employment expenses for working at home but selected to transfer income to the form for working from home due to COVID-19. To claim the employment expenses you entered, you'll need to go to your T4 slip and select 'no' to the question about claiming expenses for working from home due to COVID-19.
