Work From Home Expenses - Error Prevents Net filing

I prepared a joint return. By mistake I claimed work from home expenses on my wifes return. I corrected it by zeroing out the expenses and claimed them myself. When I tried to netfile, I received a mesage "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.

I clicked on fix and was sent to my T4  and the message said "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. 

I selected no, and was able to netfile. 

PROBLEM: My wife no longer works, but I get the same message and a request to " 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. 

I cannot net file her return and need a fix. All she claims is investment income and capital gains. 

Help!
