hello tax friends! i have been living in texas with a california employer and have mistakenly claimed my income was earned in California. OUCH! I have overpaid my CA taxes every year as a result. I am trying to at least get 2020, 2021, and 2022 refunds.
QUESTIONS
can I still file a 2020 amendment for CA?
can all 3 amended returns (2020, 2021, 2022) go in one envelope? I am shipping from out of the US and it is expensive
In the forms I printed from the turbotax desktop software I only see 540 NR, should I print something from the CA website?
should I include a letter explaining the mistake?
anything else I should know?
thank you soooo much!
