If you have accidentally deleted a return, don't worry, it's not too late! You can get deleted returns back, and it's fairly simple.
All you will need to do it go back to the main dashboard and click the "Start A New Return" window.
Next, type in the SSN of the return that was deleted, a message should appear stating: "This return was previously deleted - would you like to restore the deleted return?"
Click Yes to the message above and the return should open to the state that it was in before it was deleted.
This applies to all years of the UltimateTax software.
