I invested in a failed Kickstarter project. Where do I enter those losses?

Investment of a significant amount was in early 2023. The stated "delivery" was April 2023...then delayed. Now it appears there will not be a realization of the product as promised. 

The Kickstarter project has for all practical purposes gone dormant since November 2023. Facebook page as well has not been updated or posted to by principals of the project in several months.
