@hazanjo You just need to install the software and login to the same account that you used when you entered the License Code on the first PC.

Getting error code 608 (the license code is already linked to another account), when trying to set up on a 2nd computer.

You need to sign into your TurboTax account on the 2nd computer. After signing in you should be able to install the program. It worked for me.

TurboTax Download

@rwpeck47 What year are you trying to download? Did you buy this directly from Intuit or from a retailer? Checking your profile, I see that you have been using TurboTax Online for the past few years.
