I am having a hard time understanding the difference between the new Superseded return and an Amended return. 

My real confusion is with trying to authorize an electronic payment for additional tax that is due with the Superseded return.  On Part IX of the Information Worksheet (Electronic Funds Withdrawal Options), there is NO box to authorize an electronic withdrawal for a Superseded return.  However, there is a box to authorize electronic withdrawal for an Amended return  Should the Amended return box be checked to authorize an electronic payment on a Superseded return?  If I check the box to authorize withdrawal of funds for federal balance due, the amount due populates in the area just below the check boxes.

To make matters even more confusing, I cannot see where any of this is addressed when I run the review for the return, or in any of the letters.

Thanks for any advice you can offer.
