Those are the bias test points sandwiched in between the adjustment trimpots. You have the right location.

To be sure, it is pin#2 of R22 for V3... and pin#2 of R19 for V4???

But why it is written this in the manuel instruction:6) Probe your DMM (set to DC volts) from the test point which is sandwiched
between the R19 & R22 to ground. V3 is adjusted with the ʹinsideʹ test point.
Adjust R22 until the voltage is .350V or 350mV.
7) Probe your DMM (set to DC volts) from the test point which is sandwiched
between the R19 & R22 to ground. V4 is adjusted with the ʹoutsideʹ test point.
Adjust R19 until the voltage is .350V or 350mV. ????

Thank
