The Pasts Reminders tab is where you'll find all Instagram posts that were scheduled as reminders (i.e. not published automatically), as well as all Instagram stories. You can re-trigger push notifications from here if you miss the alert the first time around.

Tap the round avatar icon at the top left of your screen and tap on your Instagram account (if it's not already selected). Then, tap the Past Reminders tab. Here, you can toggle between Posts and Stories.
To share a post or story to Instagram now, tap Post to Instagram at the bottom of the post. (You can also access this option by tapping the three dots at the top right of the post). This replicates what would happen if the reminder were to come through now, and allows you to share the post or story to Instagram.
To add a post back to your queue, tap the three dots at the top right of the post and then tap Copy to queue. This option is only available for posts, not for stories.
On Android, it's possible to reschedule a story by tapping the three dots at the top right of the post and then tapping Reschedule. This option is not currently available on iOS.
