Basically, you can re-import the data only if you start over from scratch. Since you're using the desktop version, it's easy. Close all programs and delete the .tax2019 file in the documents\turbotax directory. Then open the program and start anew. Make sure you import from the .tax2018 file. If you import from the PDF file you will *NOT* get any information on your rental properties imported from the 2018 tax return.
