2020 Form 8606 Error

In 2020 I had a distribution from an inherited IRA (with no tax paid basis) and a distribution from a regular IRA with a tax paid basis which was converted to a Roth.  Form 8606 is calculating a non-taxable portion of each distribution which is incorrect because 100% of the inherited IRA distribution is taxable.  The 2019 version of TT handled this correctly.
