State tax filing

I help my brother-in-law with his taxes and his federal taxes were accepted on 2/12/21 and his CA taxes were rejected on 2/13/21.  Turbotax screwed up the forms somehow and corrected the issue.  Once rejected, he was able to log back into Turbotax (which corrected the error with a software update) and resend his CA taxes on 2/13/21.  After the second submission they were accepted by CA on 2/14/21.
