The license code that comes with a CD purchase of TurboTax can also be used for a digital download at installturbotax.com, but it seems the platform selected for the digital download becomes the only platform option available thereafter; for example, if I download for Windows but then also want to download for Mac, I get an error, requiring the CD. Is there a way to add to or switch the digital download platform options, seeing as installing from the CD for the same license code continues to work on either platform? This issue occurred on TurboTax Premier 2020 but I assume is the default for any edition.
