I filed my 2018 tax return using Turbo Tax Premier. This year I tried to upload the file "taxReturn.tax2018" to Turbotax Online after upgrading to the premier. Initially, it shows the progress at the lower-left corner of the screen. Once it says 100%, it still says "Uploading your Desktop File" and after a few minutes session timed out.
Last year taxReturn.tax2018 file size is around 35MB.
