"How do I recover a deleted purchase order"
Once you delete, you can't recover. It's a permanent delete in QBO.
You will need to recreate again. From the audit history log, you can get the PO data.
From the Gear icon on top, select Audit Log under Tools.
Find deleted transaction in question, click View under History column. Click Show all/Hide all button at the top. You will see the History of that transaction.
