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, note the following.
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.
