I opened a Traditional IRA Savings account with $7k of after-tax money to reduce my 2020 taxable income by that amount. All IRA contributions must be reported. That $7k gets reported on line 2 of form 8606 as Basis in the IRA and is a Deductible contribution in the year it was made. Line 1 for non-deductible contributions is "0". The headline of the form says "Non-Deductible IRAs" but that is misleading because my Deductible contribution gets reported on the form too. There is no other form to report it. Since TurboTax didn't generate the form because the the contribution was treated as a deduction I will send the form 8606 (with $7k deductible contribution on line 2) myself.
