Hi I faced a similar problem on my taxes and I was just wondering do we also need to file another form out to amend our state return or is the 1040X file enough to amend both our federal and state taxes? Also is there any additional documents needed to be filed by my parents for their own taxes? And will it be considered late if I filed the amended taxes on March 11 if it takes 2-3 months to process the amended form? Thanks!
