Open Trash in the MORE group of the sidebar. Deleted records wait there until you restore them or remove them permanently. Trash clears itself 180 days after a record is deleted.

How things get to Trash
When you click Move to trash under Danger zone on a lead, deal, listing or form, the record goes to Trash. It is not deleted yet.
Steps
- Click Trash in the MORE group of the sidebar.
- Find the record.
- Restore it, or remove it permanently.
An empty Trash says "Trash is empty". Click Back to Leads to return to your pipeline.
Auto-purge
The page shows Auto-purge after 180 days. After that time a record is removed for good, and you cannot restore it.
What restoring brings back
- A restored form brings back its submissions, and its link and embed work again.
- A deleted lead or deal returns to your lists.
If it did not work
I cannot find a record. It may have been in Trash longer than 180 days.
I do not see Trash. It is in the MORE group. Your role may not include it, so ask an admin.
