I am in California. I filed my state taxes using Turbo Tax when I was filing federal tax. So, I believe I mistakenly filed my state return as a resident.
On checking my copy of the return, it has two different forms:
1 - Form 8453-OL titled "California Online e-file Return Authorization for Individuals"
2 - Form 540 titled "California Resident Income Tax Return"
Does this mean I need to file the federal tax as well as the state tax via Sprint Tax?
Also, will Form 1040X will amend my federal tax only? If so, what separate form needs to be filled in order to amend the state tax?
