If you are using a Desktop version of TT use Forms mode to open the Calif "Excess SDI Wks" and make sure the total SDI is in line 1. Line 3 should be the excess and the credit amount. Online versions don't have Forms mode.
I just did a quick test and the excess SDI credit happened automatically as it does for everyone else. There might be something unusual about the W-2s such that TT/Calif can't get the correct total SDI withheld.
