The Arduino library folder is <home>/Arduino/libraries. This is where libraries downloaded using the library manager end up.
Do not put anything in .arduino15/packages/esp32/**. This is the built-in board specific libraries and will be removed/updated with the board.

The link above explains how to install the development repo. There are a number of newer branches in there. The esp32s2 branch includes a newer version of the touch hal. Test that branch and see if it fixes the issue. If not, post an issue in the repo.

Note, it is more likely that the paint on your board is incorrect rather than the pins being switched. AFAIK, the pin numbers are directly passed through to the touch API. Are the pins reversed if you try an analogRead on 32 & 33?

Are you using the esp32s2 branch? arduino-esp32 v1.0.4 uses IDF 3, which pre-dates the esp32s2.

ADC2 is not available while the radio is in use. When not in use, the two ADC channels give reasonably similar response, but should be calibrated separately if you want really accurate results. https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/adc.html#adc-calibra...

Preferences is just a thin wrapper over NVS. NVS is non-volatile storage. As such, it is intended to persist, and not be regularly wiped. It stores some system calibration information, along with your data, so if you want to clear a namespace, you should clear just that namespace. If you want to wip...

You aren't allocating any space in the char* to hold the result. Try initializing with an fixed length array instead of a pointer:

The esp32 includes an RTC that can work during deep sleep. Why not use that? It will not be enabled by default if you use just a gpio wakeup, but it is easy to add a deep sleep wakeup timer in addition to your button. You probably need to ensure it wakes up once a day to sync the time anyhow. https:...

Wemos D1 mini is an esp8266, not esp32. If you choose the correct board type, you should be able to upload with Arduino IDE.

Two possible fixes:
1) Add WiFi.setSleep(false)
2) Add a delay(100) at the end of your loop()
