For additional clarity, I've ammended both Federal and State returns.
I know I have to mail ammended Federal return to IRS. The State return instructions indicate to attach a copy of the ammended Federal return. I just need to know if I need to separate these in any way (e.g. staple them before putting in evelope) or just stack them in order (state on top and fed at bottom in same envelope) and mail to Franchise Tax Board. Any help is sincerely appreciated.
