Welcome to the Community, @btaylor76! 

Hmm, it looks like the Project field on the New Incomplete Task trigger for Todoist is a required field with no “all projects” option available. There’s an existing feature request for the ability to trigger on tasks added to any project so I’ve gone ahead and added your vote to that. While I can’t make any promises around when/if it will be added we’ll definitely send you an email notification once it is.

For now you’d need to create duplicate Zaps for each project to trigger for tasks across multiple projects. Not ideal I know, but hopefully helps to get things up and running in the meantime!
