BTW, the help link within TurboTax (desktop, Deluxe, Windows) says something different. The help directs you to https://www.fema.gov/disasters and instructs you to search with the filter "Major Disaster Declaration". One filter by state and locale. For mine, Texas, COVID-19 shows up:
Texas COVID-19 PANDEMIC (DR-4485-TX)
Incident Period: January 20, 2020 and continuing
Major Disaster Declaration declared on March 25, 2020
