If on AutoSave, use SaveAs immediately, before making any changes.
Best, though: Save your blank, ready to fill-in, form as a document template.
When you double-click on a template file, it will create a new document with the same content. You then save this new document. Do not use the web application for this. Word is designed to be using templates for files like this. https://www.addbalance.com/usersguide/templates.htm You can access such a template either by double-clicking on the icon in Windows Explorer or by using File > New. Once you have created a document from your template using File > New, it will show up in the suggestions when you use File > New in the future.
Look into using Workgroup templates to store collections of such templates. https://www.addbalance.com/usersguide/templates.htm#Workgroup
