I am in Illinois, bought my TT Premier from Amazon. I tried filing my taxes together(FED and STATE), and I got the same dialog box. I decided to try them individually, and the FED worked fine. The STATE gave me the dialog. After a lot of research, I uninstalled my 2019 version (still have 2017 and 2018 versions installed), and logged into TT online. I downloaded/installed 2019 Premier using my key, and when I loaded TT for the first time, it said it needed to update. Once it updated, I opened TT and was able to e-file my Illinois with no issue! I did NOTHING other than uninstall, and then re-install from TT ONLINE using my DVD key (from Amazon). I will say, however, that TT ONLINE showed my version as being 'Amazon'.
