Hello Myvoya4ger44
Please kindly note, if you want to ship your luggage to Zurich HB, upon baggage check-in, you must be in the possession of a ticket (point-to-point ticket, Swiss Travel Pass, Saver Day Pass, or similar travel pass) which proves that you will be travelling to Zurich HB later during your trip.
You are welcome to store your luggage at Zurich HB for a longer period. There is free storage on the day of arrival and the following four days. Every subsequent day costs CHF 5.
I have noticed that the relevant information is missing on the Door-to-Station product page in English and Italian language, whilst it is there on the German and French page. I made the relevant product team aware of the missing information.

Kind regards,
Roland
