Maybe you should spend more than 10 seconds Googling?

You could, for example, read the story you linked, which states: "Despite health officials knowing the man died in a motorcycle crash, it is unclear whether or not his death was removed from the overall count in the state."

So it's a nothing story, with no statement of fact included at all. Just "unclear whether or not" against repeated statements by state officials that "not."

So it was included and then removed once people noticed?

There will always be small numbers of cases of stupid coroners, clerical mistakes, etc. Finding one is not proof that there are hundreds of thousands.

We can rule out the "they're reporting everything as COVID and that's making the numbers high" hypothesis by looking at overall excess deaths - how many more deaths is the nation experiencing than is typical. A misdiagnosis won't affect excess deaths, as it counts all deaths, regardless of cause. The CDC provides a page for this:

As is readily visible in the chart, we've been substantially over the norm since late March.

(Switch the chart to New York City for an even more obvious example of how a spike in excess deaths shows up. Screenshots: https://imgur.com/a/zSkNbxT)
