Just go to EVIC where it shows Oil Life, push and hold ok on the steering wheel and it resets.
Jeep must be in RUN or the engine running.
There are other ways to do a reset, search this Forum or look in your Owner's Manual. I forget the 'other ways'.

In my opinion it is just useless information.
It doesn't know if you are using lawn mower oil or Amsoil Signature oil rated for 1 year or 15,000 miles in severe service.
I just change my oil on a pleasant Spring day and in the Fall before it gets cold.
If you drive off road then it is every 4K miles no matter what kind of oil you use or what the oil life monitor says per the Owner's Manual.
While I was still under Warranty I did exactly that so my Jeep dealer wouldn't beat up on me if my cam shaft follower bearings started ticking.

The EVIC screen needs to be displaying the oil life screen. But, I am sure you are doing that.
See if you can reset the trip odometer readings by pressing and holding the reset button. Maybe the reset button on the steering wheel doesn't work.
It all works fine on my 2014 TH. Maybe it works differently on 2019 and later.
This is what the 2019 Owner's Manual says:
Oil Change Reset — If Equipped
Your vehicle may be equipped with an engine oil change
indicator system. The “Oil Change Required” message will
display in the instrument cluster display for five seconds
after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil change indicator
system is duty cycle based, which means the engine
oil change interval may fluctuate, dependent upon your
personal driving style.
Unless reset, this message will continue to display each
time you place the ignition in the ON/RUN position. To
turn off the message temporarily, push and release the OK
button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the following
procedure.
Oil Life Reset
1. Without pushing the brake pedal, place the ignition in
the ON/RUN mode (do not start the engine).
2. Navigate to Oil Life submenu in Vehicle Info in the
instrument cluster display.
3. Push and hold the OK button until the gauge resets to
100%.
Secondary Method For Oil Change Reset Procedure
1. Without pushing the brake pedal, place the ignition in
the ON/RUN position (do not start the engine).
2. Fully press the accelerator pedal, slowly, three times
within ten seconds.
3. Without pushing the brake pedal, place the ignition in
the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.

I see it says: "If equipped". Maybe yours isn't "equipped".
