How can I download the Filed NC return PDF (Accepted 04/01/2025, $5,677 due) from TurboTax Online? My account only lets me download the amended return ($1,727 due).

Sorry Turbo Tax only keeps the last return filed.  The amended return overwrote the original return.  You needed to save a copy of your return before you did the amended return.   Maybe you can get a copy from the state.  What do you need to see?  Did you pay the first $5,677?
