The most recent mandate under the RFS was issued belatedly by the U.S. Environmental Protection Agency at the end of 2019.  The previous Administration delayed issuing the Renewable Fuel Standard apparently due to COVID but more realistically as an expression of political expediency.  For the 2020 compliance year, it was established that 20.1 billion gallons of renewable fuel would have to be blended, with a projected production of 15 billion gallons of ethanol.  It would not be possible to source the remaining five billion gallons from advanced biofuels and non-cellulosic ethanol given non-availability. Any mandate must be based on the reality that the only sources of biofuel for the U.S. are biodiesel from soybeans and ethanol from corn.

Informed observers consider that the biofuel blending mandate for the current year and for 2022 will be unchanged from 2020 given the low requirement for gasoline.  There are indications however that with a return to work, drivers will be commuting and recreational travel is expected to increase sharply from 2020 suggesting higher fuel consumption.
