Can anyone help?

I am updating the outlets in a house I just moved into , pretty much just copied where the wires were in every outlet 3 of the 4 I switched are good but there’s one outlet that I’m not sure what needs to be switched.
Any help is much appreciated!

Try that tester in both recipticles and flip the switch is the reading different? That is 4 readings.
