Not sure why you're asking me this question. Question should be to TurboTax why they advertise with Coinbase but then don't work with Coinbase to make sure what they're offering works. Only workaround I found was use Edge browser but many of us don't use Microsoft products or at least as few as possible. It's pretty standard these days to be able to use browsers such as Chrome. Two companies this large, TurboTax or Coinbase should never even matter what browser is used, since they should have enough security and technical skill to make interoperability seamless. Just strange..and concerning...it doesn't work in the first place as advertised and TurboTax points the finger at Coinbase for changing their CSV file format but Coinbase points the finger back at TurboTax for being unwilling to work with them. Ultimately it's TurboTax pasting Coinbase's logo all over their software and offering a discount so in my view, it's TurboTax's problem to solve by working with Coinbase. Or, if they can't work together for universal browser compatibility, they should pull the ads and stop offering it. Seems pretty simple to me.
But I can't answer for you what you should do. I know what I'd do and I'm looking to maybe try out TaxAct or Credit Karma next year.
