For CA SDI, Turbo Tax doesn't know if you entered something wrong or left something out. It only guarantees the calculations are correct based on what you entered.
Did you enter enter both your W2 and your spouse's W2 under one name? And only enter the CA SDI from W2 box 14? (if it was in box 19 you are suppose to move it to box 14).
Then for next year if you transfer from 2023 you should delete all the W2s and enter them again manually making sure to assign each W2 to the right spouse so it doesn't happen again.
