This reply is to a post from 2021. The entry in box 14 is not excess CASDI. It is the amount your employer deducted from your wages. The limit for CASDI is 1601.60. I had an issue with Turbo Tax not calculating excess CASDI or SDI on the Excess SDI worksheet and therefor would not transmit my return electronically. In the worksheet there is an option to right click on the entry for SDI limit and choose "Override" to enter the 1601.60. In my case and in yours the result in the next line is zero. Once I made the correct entries and closed the form the error went away, and I was able to finish the process of filing electronically. I spent an hour and a half on the phone with a TurboTax expert before figuring it out for myself.
