Project doesn't have checklists. The closest thing is the Notes field where you can include additional information about a task, you could even create a bulleted list but you won't be able to impact the task itself (e.g. start, duration, finish, etc.) by changing entries in the Notes.
Unfortunately the Notes field cannot be fully displayed, as a field column in the view, if there are multiple lines of text. But what you can do is to create a value list in a text field such as in the following:
Then in the Gantt Chart view, activate the selection list for the customized field like this
Now you effectively have a checklist.
Hope this helps.
