There are three sources of getting the stimulus money by the Treasury Department

Public Sector
Like other parts of the government

Private Sector

This includes companies, businesses and other investors

Foreign Investors

This includes the sources from other countries which invest in the US

You forget the 4th source: the Federal Reserve.
It's likely the sources you mention cannot absorb the securities, therefore the Fed has to "print money" via Open Market Operations (OMO) and buy it.

It's recommended to watch the video till the end, both for OP and the doomsayers here to know what the "printing money" is all about.
