State tax filing

As long as you have not submitted your tax return, you can still edit them.  To do this, click on State on the left side menu once you are signed into your return.   Then up top, click on Your State Returns.  From that page, you should be able to click on the Edit button.   If the Edit button is not working, try refreshing the page or log out and then log back in.  

If you have already submitted the returns, you will be able to edit them only if they get rejected.  If they are accepted, you will need to file an amended tax return.
