Your Federal and State returns don't have to be filed together, so there is no problem with this situation unless you also electronically filed your State return at the same time. If you didn't file your State return, simply make the changes on your State Return, and print and mail it. If you did file your state return, you'll have to file an amended State Return. I would suggest waiting for an adequate period of time before filing your State Amended Return. That could be up to two months or so for them to process a paper return. My concern is that you could cause confusion in the State Dept. of Revenue by having a Return and an Amendment "in the system" at the same time. It might be possible to call them and find out more information.
