Sorry you're having trouble. Unfortunately, I don't think your issues can be completely resolved on this user community bulletin board. This is not a direct route to TurboTax Support, so no one here can do anything about your charges here anyway. You should phone TurboTax Support so you can explain everything to them in realtime, and they can question you. They can push you any 2018 state downloads you paid for so you don't have to pay for them again.
And if you were charged twice for your 2018 product, TurboTax Support should be able to straighten that out.
If your 2018 tax file has state returns in it, then you have to install the state software before you try to open the *.tax2018 data file, or you'll get that error 190.
TurboTax Support hours are 5AM-9PM Pacific (8AM-12 Midnight Eastern) 7 days.
You can use this contact form to get an incident number and phone number. When filling out the form, in the dropdown menu be sure you indicate you are using the CD/download version.
