After editing a tag wiki, the notification that indicates there is an un-reviewed item is visible… but you cannot review it, as you suggested the edit.
This is normal. You have the access to moderator tools privilege (unlocked at 2k rep on beta sites and at 10k on graduated sites) so you will get notifications for normal suggested edits excluding yours and you should also get notifications for suggested tag wiki edits that are yours. There are no exceptions as these are shown to everyone with the privilege.
You can also get this notification in the edge case where you gain the edit privilege while one of your suggested edits is still pending.
When you suggest a tag wiki edit, you won't be able to review it, that wouldn't make any sense.
This is different than what happens with normal edits, where you do not seem to be notified of a review when you edit an answer or question. (as it should be)
You also have the privilege to edit questions and answers without needing approval so neither you nor anyone else will get notifications for these edits since they are applied at once.
