The place where information for handouts can be added

notes

Explanation:

You need to place the information for handout in the notes page not just in the slide but also in the speaker notes, And when you will be planning to make use of the notes page as a handout, you need to mention the notes you want for the handout inside the notes pane, which is at the bottom of the slide. And if you will be putting the details in the notes pane, then your audience will get them in the handout.
