Something to clarify:
- If you are using QGIS after 3.2.0 or later, you needn't install OTB plugin as it is deprecated.
- For most users, please follow the path of the folder I showed above. It is a time killer issue to get the error and parameter wrong all the time.

When the field boundary is available (customize the segmentation):
Sentinel-2: create a composite to compensate for the cloud cover
- Feature extraction: assign statistics for image values
- Training data
- Validation data
