If I sell ISO shares (which is a qualifying disposition), I can enter the correct AMT basis by entering the difference between the AMT gain and Regular gain through:
Personal -> Other Tax situations -> Alternative Minimum Tax (AMT) -> "I exercised ISOs in 2024... Or I sold ISOs in 2024..." -> Skip "Enter your ISO adjustment" -> "Enter the amount of your ISO adjustment that was a long-term capital gains/losses
Doing this allows TurboTax to correctly fill in Form 6251 2k (Disposition of property). When I start my California taxes, I would expect TurboTax to also fill in Schedule P(540), line 9: Adjusted gain or loss but it does not which results in a much higher California tax.
How do I get TurboTax to do this or do I need to do a manual override?
Also if the AMT gain is a loss, TurboTax will correctly carryover the loss for the next year. But it does not do this for California which means taxpayers may end up paying higher California taxes next year.
