Welcome to the community! Would you mind having a look at the discussion that has happened in the past, it should help you learn on how to make a PDF copy of your survey form designed in KoBoToolbox:
Please note at the moment, KoBoToolbox does not support directly saving the questionnaire in Word Doc, hence after having a copy of your questionnaire in PDF format you could use some third party software (or some online conversion sites) that converts the PDF questionnaire to Word Doc format.
GOOD DAY!
