I don't think it possible to get any amount entered on TurboTax's 1099-R form to appear on Schedule D line 13. As far as I know, amounts entered in box 3 of Form 1099-R will only propagate to Schedule D if the distribution is from a charitable gift annuity reported with code F in box 7 of the Form 1099-R and even then it will appear elsewhere on Schedule D and will be excluded from Form 1040 line 4d. The only source of an amount on Schedule D line 13 that I'm aware of is box 2a of a Form 1099-DIV.
