You can do it and print and mail-in your state return to your state tax board. However, to create your state return you'll have to enter your data in Federal section of the interview and it should be exact same entries like in your tax return you already filed.
I was having so much trouble with my return and trying to detach invalid documents that I created a new one but what happened is it combined everything now I have 2 returns that are not right. I need to delete and start over
