I e-filed my 2010 federal return couple of weeks back and even got my refund deposited. I had not filed my 2010 California return, as it needed to be paper filed.
Couple of days back, I discovered that I forgot to take a property tax deduction. I have now filled the 1040X and about to mail it with affected schedules to the IRS.
My question is about how to file my California return now. I guess I have two options.
- Use the amended federal numbers for filling up the California form
- Use the original federal numbers, original 1040 and file the 540 using those. Follow it up with an amended 540X form after couple of weeks.
I was thinking of going with the first option as it is straightforward and I can add a cover letter to explain. Is this the right way? Sorry, I could not find any guidance on the government websites.
