What “Coordinate Transformation Matrix” must I use to get my touchscreen working correctly?

Can someone please assist me, I’m pulling my hair out here. I’ve been trying for days to figure this out.

Ubuntu 18.04.4
Display Set: Right
Touch Frame: IRTOUCH System

If i use the following command in terminal to try calibrate my touch i get the following results

xinput set-prop "USB Touchscreen 6615:0001"  --type=float "Coordinate Transformation Matrix" 0 1 0 -1 0 1 0 0 1

My left/right is correct but my Up/Down is incorrect

if i use

xinput set-prop "USB Touchscreen 6615:0001"  --type=float "Coordinate Transformation Matrix" 0 -1 1 1 0 0 0 0 1

My left/right is incorrect but my Up/Down is correct

I’m trying to figure out what combination to use to configure my touch correctly. I’ve tried installing the driver which i downloaded from the manufacturer but that also does not work.
Does anyone know what “Coordinate Transformation Matrix” i must use to get my Left/Right and Up/Down working correctly.
