if you are amending 2019 to get a refund, it's probably too late since you normally get 3 years from the applicable due date. which would have ended in 2023
if you owe this is no time limit for the iRS to come after you.
it is unlike 2019 will work, I'm surprised any year prior to 2021 works because Turbotx has shut down the update servers. so neither the original program nor updates are available.
this was supposedly a solution that worked but it comes from a post for 2023 and we don't know what year the OP was trying to reinstall or wether it still works
Rename folders in the folders below for TY19 to something else and uninstall and install.
C:\ProgramData\Intuit\TurboTax
C:\Users\[current user]\AppData\Roaming\Intuit\TurboTax (change view to see hidden folders)
