If you are able to move the little white circles on the calibration screen smoothly up and down, that's a sign that it's working.
If the automatic stick detection gets it wrong, you can click on the circle that you see is the correct one (instead of clicking "ok").
When you get to the trim screen, you will be able to see if the stick movement is recognized correctly.
And, in case you haven't seen it here's a document describing how you need to setup the Taranis for it to work correctly on Windows:
