Slightly tricky. Are you using Turbotax online?
It depends on your state. Here's why.
When you prepare a federal amended return, you generate a new tax return with all the appropriate forms and schedules, plus a form 1040-X cover page that summarizes the differences between the original and amended return.
You don't need to file an amended state return, you just need to file a correct original state return. But how to get that? When you prepare the amended federal return you will also be able to print an amended state return. If your state uses the same format (all forms and pages plus a cover page) then you can just throw away the cover page and file the rest as your original return. But if the state's amended form is different, you might have difficulty printing an original state return with all the required original parts.
It is also possible that if the amended state return is different, you could print it and throw it away and then go back on the web site and "print a copy for my records" and that might be a new "original" return with all the right pages. But I don't know if Turbotax online works that way.
You can certainly do it in the desktop version,, installed on your own PC or Mac from a CD or download. Just save a duplicate copy of your data file. Make one data file the correct original state return, and add the income without amending, and print a new copy of the state return. Make the other copy of the data file your amended federal return.
What state is it? Maybe a state specialist can help you.
