"is that for ANY disaster distribution or only for the 2020 Covid one?"

I agree, and the first thing I looked for is how it is worded. The IRS has very clearly differentiated "coronavirus" or covid disaster, from qualified disaster, as seen in the 8915-F instructions.

https://www.irs.gov/instructions/i8915f

"A coronavirus-related distribution can't be made after 2020. Also, a distribution is not a qualified 2020 disaster distribution or a qualified 2021 disaster distribution if it is listed in Distributions that are not qualified disaster distributions, later. See Limit, later, for the dollar limit on qualified disaster distributions."

IRS has instruction changes:

"If you downloaded the Instructions for Form 8915-F (Rev. January 2022), please be advised that those instructions have been replaced by the Instructions for Form 8915-F (Rev. February 2022) to correct the disasters listed in Appendix B under the Table for Qualified 2020 Disaster Areas. The revised instructions also address the lines on which to enter income on Form 8915-F for a decedent who has spread the income from their distribution(s) over 3 years and who dies before the 3-year period has ended."

"Reporting the remaining distribution amount when the taxpayer has died

On page 2, in the Caution under How Is a Qualified Disaster Distribution Taxed, we added this sentence: “Include the remainder in the line 13 and/or line 24 totals, as applicable, of your 2021 Form 8915-F.”

Please download the  https://www.irs.gov/pub/irs-prior/i8915f--2022.pdf for the revised text."

The last comment I want to make, that was nagging at me yesterday, was the 2021 tax year prep seemed to indicate there were no 2021 qualified disasters per the IRS process. I see nothing like this in the table of disasters. I wasn't going to fact-check the OP, though.
