Here’s a summary of the connections for Net 20 as defined in your schematic:
CH2 VDD (connected at pin P1 of the Power Net Portal)
R1 (connected at pin P1)
R2 (connected at pin P1)
R6 (connected at pin P1)
C3 (connected at pin P1)
U1 (the CH224K USB IC, with its VDD pin connected)
R3 (connected at pin P2)
Each of these components is linked by the net named “Net 20,” which distributes power (VDD) from the CH2 VDD portal to the associated resistors, capacitor, and the power input of U1.
