It is pending in the manga queue: https://myanimelist.net/manga/114918/The_Life-Changing_Manga_of_Tidying_Up__A_Magical_Story (presumably with a couple things that need to be fixed).
If you would like to search for a manga in the queue:
1. Go to https://myanimelist.net/panel.php?go=mangadb&do=add manga submission page
2. Under 'Relations', click on 'Find'.
3. Type in the name of the entry.
4. You'll see a list of IDs. Find the correct idea, and copy it to your clipboard.
5. Type 'https://myanimelist.net/manga/[ID_of_entry]' (without brackets) in your search bar.
site:myanimelist.net "name_of_manga" in Google (any search engine should work). Including the quotes will search for exact titles.
You can check up on this thread to see when things are approved: https://myanimelist.net/forum/?topicid=1752366
However, keep in mind that there are over 7,000 entries in the manga queue and only a couple active manga database moderators.
