Sounds like you file an extension with $0 taxes due and when you printed it had a balance due.
You cannot amend an extension, unfortunately. The extension is for filing, and since you haven't filed any forms, there is nothing to amend. If you would like to change the income that you put with the extension, it is not necessary.
A tax extension doesn't give you more time to pay taxes you owe. If you owe on taxes and you need to file an extension, you must pay when you file your extension. Otherwise, you'll also have to pay interest and late penalties. So when you file your return if you do not actually owe no problem. If you owe the interest and penalties will start at due date of return because you did not pay with the extension.
Check your return, if you started one. The amounts shown there will automatically transferred to the extension.
