Can i reverse a deposit i didnt mean to delete?

There is no undelete or reverse. There is no user backup to restore from. If it were based on Excel there might be a back button so to speak but you must recreate the deposit as you did to begin with.

If the original deposit was created from Undeposited Funds rest assured that deleting the deposit did not delete the payments sitting in Undeposited Funds, waiting for you to make the deposit all over again

How do you make the deposit all over again?

Here is a detailed article to help you enter the deposit. (see link below)

If your situation is the same with what john-pero has explained above, then go back to the Bank Deposit page. Then, perform the process from there by using the link provided by Pemberton-Cobb.

Otherwise, you can use the audit log to retrieve the deposit information. It shows transactions you've recently deleted.
