Yeah the original instructions aren't great, because deleting that C:\Program Files (x86)\Turbo Tax\Deluxe 2019 directory seems to wipe out record of you downloading the state forms.
I was able to get my deleted folder from the Recycle Bin and copy the directory inside of it that seemed to correspond to my state forms (the directory name was wvi_19 for the WV forms). When I restarted TT, it acted like my state was already downloaded and good to go.
Maybe check your Recycle Bin for the original Deluxe 2019 directory and copy over your state folder inside it to the C:\Program Files (x86)\Turbo Tax\Deluxe 2019 directory? Then restart TT?
