I had a problem with prior year information coming over too. I got a new computer and loaded turbotax 2018 on it along with the data files but not the turbotax 2017 software. Only some prior year data transferred in. So then I had to load turbotax 2018 on my old computer start my return on it in order for all my prior year data to transfer. SInce my old computer was slower I then copied the 2018 data file from my old computer to my new computer and it worked fine. Quite a hassle though....
