I found a mistake when reviewing my return. I had owed money now I have a refund, but the payment voucher forms are still stuck in my returns. How do I get rid of them?

If you return was not submitted, make sure to correct everything this will update your federal refund amount. 

It might still print out form 1040-ES these are for estimated tax payments, you can find more information about it here
