What's wrong with this Turbotax? I've copied example for backdoor Roth conversion exactly and it says traditional distro is taxable but I had no prior traditional.

I'm over 55.  Stood up new Traditional with $6500 after-tax money.  Never had Traditional before.  Converted to Roth as soon as I could, about 2 weeks.  No growth of the $6500.   I've followed the example posted here from previous years on how to do this but Turbotax is still showing the $6500 as "taxable amount" on the Form 1040 worksheet.
