Bought a $20 OBDII scanner from Home Depot cleared the P0420 and reset all flags except EVAP.

Had to drive about 800 miles to clear all flags as my high-speed driving habit did not fit Toyota's driving regime.

Removed the O2 S2 extension, drove 2 miles to the nearest STAR SMOG test before the ECU set any flags. The guy hooked up the car to his SMOG station and said, this car had failed SMOG once, He ran tests, all pollutant tests passed.. The guy did not inspect the engine or exhaust system. I could have brought the car to him in the first place.

Put the extension back on so ECU wont pull the code again.
