I'm working on amending 2021 federal/CA tax return
I know I should print and mail for federal amend return for 2021
But not sure for CA, Can I still use my turbotax 2021 to efile my CA 2021 amend ?
and For Federal amend,
Actually I need to send them 2020,2021,2022 amend.
Do I need to send each year in a separate envelope or
as long as I stapled and attach coversheet for each year separately, it is okay to send them all in an envelope ?
