Getting the same problem others have when attempting to e-file federal taxes. Once the transmit button is pressed, Quicken comes back with "FAILED_VALIDATON. there is an update available for your version of TurboTax. Before you can file electronically, you'll need to get this update. To do this, go to the Online Menu and select Check for updates". I have the checked for the latest update and appear to have it (4/29/2021); Turbotax says "Your software is up to date". I've tried manually updating and uninstalling/reinstalling; still get the same Failed validation message. Help! it's almost 17 May when taxes are due!
