Why does 1099-R Summary Form shows Nontaxable Distributions for Sales Tax Deduction on line 40? This makes no sense.

Why does Turbo Tax change IRA Distributions on 1040 Line 4a and line 4b

TurboTax may show different amounts in Line 4a, which is for total distributions and Line 4b, which is the taxable amount, due to various reasons.

For example, if you moved money from one account to another (rollover), the total amount will appear on Line 4a because it was a distribution. However, Line 4b will have a zero (0) because it is not a taxable event. Or, if you have basis in your IRA, the total amount you withdrew will appear on Line 4a, but only the taxable amount will appear on Line 4b.

Because TurboTax may use different Worksheets to determine if you qualify for various deductions, to verify that your numbers are correct, look at your Line 4b. If that amount reflects the total amount of taxable income you expect from your retirement accounts, then the calculations are correct.

1040: Line 4a is the correct RMD amount. Line 4b should be $2K - a $2K QCD. Instead there is a $9K discrepancy.

This discrepancy is coming from Form 1099-R Summary- under the Subheading "Nontaxable Distributions for Sales Tax Deduction." It is in Line 40 "Nontaxable IRA distribution' that the erroneous $9K shows . Line 40 needs to be zero.

As I can't physically change it to zero-- looking for ideas of how to fix it. TIA
