Netfile Error Message - Work from home expenses

Hi there, 

 

My return is complete, I go to file and I get this error message. 

 

"Specify the employment income you want to claim employment expenses on for working at home due to COVID-19. This can be done by selecting ‘yes’ to transferring employment income to form T777S in the applicable T4 slip"

 

The problem is when I go into the T4, there is no option to select yes in the T4.  I have selected "yes" to Will you claim employment expenses for working at home due to COVID-19 for income on this T4?  given that is the only option to select yes in turbo tax. Can anyone point me in the right direction to fix this error?
