If you've accidentally deleted the deposit, you'll need to re-create it. Doing so will bring the transaction back to your register. It will also show on your Reconcile page.
To locate the details from the transactions you deleted, you can check out the Audit Log. Here's how:
Go to Gear icon, then Audit Log.
Click the Filter drop-down, pick the dates when the transactions were deleted, then choose the Show only these events radio button.
Tick the Transactions checkbox, then tap Deleted/Voided Transactions from the Show drop-down.
Press Apply.
You can use the information displayed here to re-create the transaction. Be sure to change the transaction's status in the register back to R for Reconciled. Then, you can already continue reconciling the account.
