I bought TurboTax Deluxe 2019 and used it for my tax return of 2019. Now I want to amend my return for 2019. So I reinstalled the TurboTax Deluxe 2019 software and tried to activate it with my original activation code. However, it shows "All available activations for that code have been used. Error code: 603". I believe I was the one who used the activation. But does that mean that I can never uninstall the TurboTax software? Because if you reinstall it anytime later, your activation code will be invalid anymore and you need to buy a new one. Is this the case?
