Default 7th Gen P0134 and p0139 codes

Hi,

was hoping someone could verify P0134 and p0139 codes ó Iíve watched different YouTube fix videos and they seem to contradict the fix/code.
P0134 is up stream and this is the sensor accessible from the top, located right when you open the hood on the engine in the middle of the heat shield.
P0139 is the downstream sensor and can only be replaced from UNDER the vehicle.

Is is this correct?
(Iíve found videos stating p0134 is fixed replacing downstream, under vehicle. This seems wrong)

thanks!
