This is asked in another topic:

"Although the initial provision for penalty-free 401k withdrawals expired at the end of 2020, the Consolidated Appropriations Act, 2021 provided a similar withdrawal exemption, allowing eligible individuals to take a qualified disaster distribution of up to $100,000 without being subject to the 10% penalty that would normally apply. This extended the timeline for penalty-free distributions through June 25, 2021."

There have always been provisions for disaster withdrawals. What there is for 2020 only is "covid" disaster.
