How do I fix an already amended federal return that was rejected? I look all over the TurboTax website and app and there’s no option for me to fix or amend it!

It was rejected due to a PriorYearSpousePIN number, which I do not know that PIN. Since is was already an amended return, due to filing status, turbo tax doesn’t show me any “Fix” “Amend” or any other kind of option.
