Hello,

I usually use the 1up 1dn harmony and set them to record to their own tracks.

I also use the "follow the chords" setting for the generation of the harmonies.

Make sure you use a clean, dry, in-tune mono vocal track as the guide track.

You can add FX to each harmony part in the final mixdown. If you have reverb recorded on your guide track, the TC will add pops-n-farts in the harmony generation.

Trial and error.
