Nothing is wrong with TurboTax . You probably failed to enter the $6,500 contribution in the IRA contribution section and mark it non-deductible.
If it was a 2019 contribution made *in* 2019 before Dec 31, 2019 then it should be on line 1 of a 8606 form and will be used to offset the tax in the line 6-8 calculations.
[HOWEVER, if it was a 2019 contribution made *in* 2020 *for* 2019 then it will also be on the 8606 line 4 that will exclude it for any 2019 conversion because it can only be applied to conversions made in 2020 and later. While you can make 2019 contribution up to Apr 15 2020, the non-deductible "basis" cannot be applied retroactively to the prior year. You also cannot convert retroactively so if the conversion was done in 2020 the you must report in on yiu 2020 tax return next year.]
