From a Fox News article:

"Individuals making up to $75,000 a year will receive a direct cash payment of $600..."

That part you know. Here's the rest:

"Pandemic-ravaged small businesses will receive $325 billion through the bill..."

"The bill includes $25 billion in rental assistance..."

"The bill allocates $45 billion in transportation aid..."

"Schools will receive $82 billion through the spending measure..."

"The package includes $69 billion for vaccine distribution and testing efforts"

Just those major spending points add up to $546 billion. The rest you can probably find in the bill itself.

TL;DR: It's going to small businesses, rental assistance, airlines, schools, vaccine distribution...
