I have amended tax return for 2020. My federal return has been accepted and now I am asked to mail Amended form 540 NR (along with the money order or check) as well as few other documents to the Franchise Tax Board.
What is the Due date for CA state amend tax return?

The due date for California returns has been changed to May 17, 2021. If they receive the amended return after the due date, you may need to pay interest and penalties.
