I have the identical question! Since Intuit has been no help, allow me to guess the reason...
When doing 2018 taxes, we filled out in excruiating detail the itemized deductions, but when TT decided the standard deduction would be better, it decided NOT to include the paperwork we did in the saved file. Therefore, no Itemized deduction worksheets or Schedule A.
So, re-install TT2018, and re-load your ...tax2018 file. It's in there, but you might have to look for it in Forms.
Now I'm trying to determine how exactly to get all the forms that were jetisoned back into a complete PDF where they can be reviewed.
