Off Guardian cites an IFR of between .04% and .5%. They get their data from SWPRS which is a COVID skeptical source. Maybe we shouldn't trust it.

But here's the CDC site listing total estimated US cases of 120.2 million and 767K fatalites: IFR = 0.6% https://www.cdc.gov/coronavirus/2019-ncov/cases-up...
For some reason, they don't list this 0.6% number anywhere clearly on the page, although it's obviously THE important number you would want to know. They leave it to you to do the math. Perhaps the number is not impressive enough to protect public health. Perhaps that number is a threat to national security.
Johns Hopkins has an estimate of 1.6% for the US. So who do we trust? How can these numbers vary so widely? https://coronavirus.jhu.edu/data/mortality
