Error Code 603 Turbo Tax 2020 & 2019

ewhite23161 — Tue, 24 Feb 2026 06:02:36 GMT

I upgraded my laptop and reinstalled Turbo Tax 2019, 2020, 2021 & 2022. Turbo Tax 2019 and 2020 give me error code 603 even though they have only been installed on my old laptop. Those years on my old laptop I would also get error code 603 but it would eventually activate again. Today on my new laptop I spent over 30 minutes with support and still did not get the error resolved. They insist it has been installed over 5 times and it has not. I am a long-time user of Turbo Tax and am extremely frustrated that it could not be resolved.

Anybody else experienced this?

I followed the process and I can now access 2019, but I get the same message with 2020.

It has been an issue in the past that this message would appear. Has it had you enter the license code on each uninstall/reinstall? If so, this can cause the issue. It would be best to give us a call, so we can possibly reset the account to allow an additional login. @ewhite23161

I spend over 30 minutes talking to the support line and got nowhere. I will try again.

After working once, 2019 now gets error code 603.
