This is all very good information. I think you were the one who pointed me to using What If when last year I wanted to see what my 2018 return data would look like with the new tax law. Using some assumptions, I have to say doing the real 2018 now is such a close match. Very good analysis.
So this sounds like I can use a copy and somehow remove state #1 and add state #2. And nothing will happen to my original return (I do back up as a 'save as' and then copy the whole folder to a thumbdrive as backup.)
Thank you once again !!!
