You can download the final manual update for 2018 TurboTax from the following link.
https://patchdelivery.turbotax.intuit.com/w_perrelsuperpatch_ttax_2018.920.0100.exe
BUT,
1. This is unofficial and not supported. If you have any problem with it, there is no way to get help. Intuit (and I) will not accept any responsibility for anything that happens from using this download.
2. There is no way to get updates for the state software for 2018. If you have to do anything with a state tax return for 2018 you cannot do it with TurboTax.
Sorry, 2018 is no longer supported.
I still see the 2018 version in my downloads folder in my Turbotax account, and I believe the download is automatically updated to the most recent patch. So Turbotax has it, even though they officially don't support it. You would have to call customer support and see if they will do a deal for you.
