I e-filed the 2025 tax year 1040 on 03/28 after previously filing an extension. Both the extension and the original return have been accepted by the IRS and the state. I am trying to create and e-file a superseding return in ProConnect, and it's forcing Form 1040X to be created and printed. I tried two ways

Copy original return> Misc Forms>Amended Return (1040X)/Superseded return> Check Box Superseded return (Amended return is not checked). The system creates a critical diagnostic error with a recommendation to select an amended return

Amend return>Misc Forms>Amended Return (1040X)/Superseded return> Check Box Superseded return (Amended return is not checked)

The critical diagnostic error mentions that 1040X must be included in the superseded return. Is this correct behavior?
