Coronavirus cancelation

Hello, 

My guest didn't cancel their booking, afraid of being penalised with cancellation fees. 

I mark their booking as 'no-show' and declined the cancellation fee, but I don't know if this will make my guest have their money back. 

If I or you can mark this booking as cancel, I see now that the fee will be refound, right? 

But for me is not possible anymore to mark this booking as cancel.

I will really appreciate some help. 

Thanks
