I have used TurboTax Deluxe for my 2019 Tax Return (filling jointly with my wife). We recently (November 2023) got a notification from the State of California Franchise Tax Board that our filled taxable income was erroneous and we now owe a substantial amount of additional taxes and penalty interest.
Looking at the filled Tax Return for that year, there is indeed was seems to be a glitch in the taxable income, which appears to have been caused by an amount entered in Item 14 (California adjustments – subtractions. Enter the amount from Schedule CA (540),Part I, line 23, column B).
This has drastically decreased the taxable income for the State tax return. The problem is I have no idea where this amount is coming from nor how it has been computed (automatically?), and it doesn't match anything from my or my wife's W2. So now I am tempted to think this was an issue with TurboTax, unless I am proven otherwise.
Can somebody from TB team help me with this matter? Thank you.
