No solution that I could find from TurboTax.
I finally went into Forms View to the balance sheet, and added a line item to income adjustments that said "EIDL GRANT, TAXABLE IN CA, BUT NOT FEDERAL" I don't guarantee that's the "right" way to do it, but am hoping that the CA authorities will have mercy on my soul for trying to do the right thing and not penalize us too much.
It would have been really nice for TurboTax to have handled the EIDL correctly, since there have to be numerous businesses in CA fighting this problem. C'est la vie.
