Hi S Hartland,
You can review the Audit Log to see the details of the transaction. Then, manually recreate it.. Let me guide you how.
- Click the Gear icon in the upper-right corner and select Audit Log.
- Look for the deleted transaction and click View.
- Click the arrow on when it was created and deleted.
- Take note of the transaction details.
- Recreate the transaction manually by clicking the Create menu (+).
Once done, go back to your register and change the status to Reconciled (R) manually. For the detailed steps, please check this article: How To Reconcile Transactions.
