Any retirement contributions made through the partnership should have been reported on Schedule K-1 (Form 1065) with code R in box 13 and your net earnings from self employment supporting the contribution reported with code A in box 14. Contact the preparer of the Schedule K-1 for a correction.
(If the K-1 is Schedule K-1 (Form 1120S) is from an S corp, it's not from a partnership and your contribution should have been reported in box 12 on your W-2 from the S corp and would be entered only in box 12 of TurboTax's W-2 form.)
