@dmertz My reading of both the 8606 instructions and Pub 590B says the worksheet is only used if the IRA contribution is only partly deductible due to income deduction limits. Simply choosing to make the entire contribution non-deductible should always use the 8606 and never the worksheet.
The line 4 instructions say that you can choose to make the contribution non-deductible and "Although the contributions to traditional IRAs for 2019 that you made from January 1, 2020, through April 15, 2020, can be treated as nondeductible, they aren’t included in figuring the nontaxable part of any distributions you received in 2019."
It also says: "If you used the worksheet Figuring Your Reduced IRA Deduction for 2019 in Pub. 590-A, enter on line 1 of Form 8606 any nondeductible contributions from the appropriate lines of that worksheet."
I read that to day that if part of the contribution is not deductible because it is "reduced" only then is the worksheet used.
Is this a TurboTax Bug?
