Form 5329 line 2 reports some of my 401K dividends with exception code #12, meaning that the income was wrongly indicated on the 1099-R as taxable because I'm over 59 1/2 years old. This code indicates the 1099-R uses code 1, J or S. However, none of these codes are on the relevant 1099-R (it is code "U") and none are entered in TurboTax (only code "U"). How can I let someone at TurboTax know about this error in their software? (I am over that age and not subject to the extra 10% penalty tax, but the dividends are taxable at the regular rate.)
