So people who are still employed, but can't (or shouldn't) leave their homes still have some money, probably more than usual.
But the primary answer to that question is the same as it's been for the past couple decades: the people with the money are, well, the people hoarding all the money. The owners, the (big) employers, the people at the top.
As has been reported various places, just as an example, the airline industry spent the last decade spending something like 80-90% of every dollar they made buying back stock to enrich their executives. That's why they don't have anything saved for a crisis like this, and that's who has all the money now.
Not to minimize the impact on companies and people who are seeing drastically reduced demand, but it's a serious overstatement to say that all companies and people are.
Banks manage money but that’s not the same as having that money on their own balance sheet. Banks can and do go bankrupt.
