I amended my 2019 tax return via Turbox tax, and my federal tax return has been accepted. But I don't know which forms should I include in my mail to amend my California state tax return.
In the document I downloaded from Turbo tax, there is a form 8453-OL, a form 540, a form schedule X and a form 3514. Should I mail them all? And should also include my federal tax return?
