Honestly I don't think automation is going to be a big factor right now. You automate when the costs of automating are lower than the costs of just having someone do that job. With high unemployment wages will fall and thus getting cheap labor to do your tasks becomes much easier than automation. Especially since it turns out that a lot of low skill labor is only low skill for humans, while a machine may be able to do the strict register duties of a cashier job it cannot also stock shelves, watch out for crime, answer questions, etc. You could install separate machines for all of these tasks but that'll get very expensive quickly. Generally anything that gets near customers, even if it's just moving to the same shelves, is going to be tricky for a machine to do accurately and safely. A robot nurse would have to be insanely complex to match the abilities of a human nurse.
And ultimately, how much would automation help with the pandemic? Businesses get shut down because they're unsafe for consumers and factories still need engineers to maintain the machinery.
