Hi there, @Cheri67. I'd be glad to assist you with reverting the deposit deleted by mistake.
If you recorded the deposit manually, you'll have to recreate it. If it's made up of payments from the Undeposited Funds, this will be returned to this account.
If you need information about the deposit, you can review the Audit Log for more details. Here's how:
Select the Gear icon.
Click Audit Log.
Under Events, you will see Deleted Deposit for the item.
Select View, under History, for the deposit.
From here, you can review the details of the transaction.
Moreover, if this deposit came from your bank feeds, it will return to the For Review tab. You can add or match it again.
Select Banking on the left navigation menu.
Locate the deleted deposit under the For Review tab.
Select Add/Match.

Hope you’re doing great. I wanted to see how everything is going about recreating the deposit you've mistakenly deleted. Was it resolved? Do you need any additional help or clarification? If you do, just let me know. I’d be happy to help you at anytime.
Looking forward to your reply. Have a pleasant day ahead!
