Error 190 indicates that you are attempting to open a .tax2018 file that contains one or more state returns. Yet the version of TurboTax you are using does not have the necessary state modules installed. If so, then you will need to start a mock return in order to download and install the state modules needed. You will not be able to open any tax return with a state in it, until you have installed the state modules for the correct states included in the .tax2018 file.
