Maryland parents and child, but child is subject to kiddie tax and had CA income.  CA Form 3800 is asking for parent's tax from CA 540 or total CA taxable income.  Parents don't file CA tax returns.  What is supposed to be done?

Kid is in college in affected county.  I assume that means we can delay the nonresident filing until 10/15/23?

IRS came out and said they also would delay for affected counties, but kid is a Maryland resident with nonresident CA income.  Assume on the safe side that filing should be 04/18/23 and not delayed?
