While Amend Download today, perhaps NOT ready for at least 2025 Amend (when already filed/processed by IRS & State)

Good news (of sorts) is Amend download happened today (I want to amend my 2025 returns Fed/State that are already processed and refunds received). However, TurboTax instructions note that both Fed and State should be starting back at "0"...yet while my State shows 0, the Fed shows HUGE $$$ owed.

So what do I do now?

I tried inputting the two items I had failed to report (small long term capital gain and actually a reduction in my dividends from what I reported) but still then shows a HUGE amount of tax owed that is crazy. I did NOT save this before I exited!
