What kind of check box is it?
A form control?
or an Active X control?
If I can recommend.
It can help us all if you upload an Excel file (without sensitive data), no picture.
* Knowledge of Excel version and the operating system is a must have if you want to proposing a reasonable solution
(Example: office version eg 2016 or 2019 or 365 web or 365 pro, etc) and your operating system (eg Win10 (2004), Win 10 (1903), Mac, etc.).
Here is a simple solution in the dark:
When document protection is on, (Filling in forms),
each box can activated or deactivated with a single click to be activated.
If that doesn't work, the whole document is probably protected.
But since I don't know what exactly it is, it could be anything if it isn't.
Thank you for your understanding and patience
Hope I was able to help you.
