I did a quick search and I think you might be getting your information from articles like this:

Fact check:

It looks like Biden's contribution is about $2 trillion to families and individuals. Counting the previous administration: another $2 trillion to businesses, $1 trillion to state and local, and $1 trillion to healthcare and other programs, for about $5-6 trillion total.
Worst case, that's about $18,000 per capita for 332 million people in the US. Best case, more like $6,000, since much of the stimulus was in the form of payroll loans that businesses were supposed to pay back, although much of that has been forgiven. Without knowing more details, the best I can estimate is the logarithmic mean, which is about $11,000. Spread over 3 years, that's just under $4,000 per capita per year.
Note that this is less than the $3,000 per year that I got in Pell grants to attend college in the late 90s, when money was worth about twice what it's worth today. At a $23 trillion US GDP, there's $70,000 per capita to play with, so $4,000 extra per year would raise per capita income by 5.7%. High yes, but not much higher than a typical 3% inflation. Especially when much of the world was out of work for a year or two during the pandemic.
The real culprit is corporate price gouging and speculation:

I noticed that Google and even DuckDuckGo have ranked this information so low that hysterical headlines totally dominate search results. It will be interesting to see how investigative journalism traces these knee-jerk headlines to their sources. Although I doubt that any titans of industry or politicians will be unmasked before the next election.
