I will be mailing my forms, but I need to change a few things I forgot. It was not transmitted or mailed. How to I change it without doing an amended return

I have not filed yet for 2018, but I can't go in to change anything without doing an amendment.

You need to click that you want to "add a state" or "file an amended tax return." 

While you won't actually do either, this will allow to your make the changes you want to your tax return before printing again to file.
