Transmission didn't go through FAILED VALIDATION because there is an update for your version. HOW DO I GET THIS UPDATE? I do not see Check for Updates anywhere

TurboTax Desktop for Mac normally prompts you to run updates when you log in. Try logging out of TurboTax, restarting your Mac, and then log back in. If there are updates, TurboTax should prompt you to download them. Check your Internet connection as well.
