I receive a K-1, not a W-2. On my K-1, 401K elective deferrals are in Box 20. Where do I enter my $18,500 contribution to my firm's traditional, qualified 401K to deduct?

Your Schedule K-1 must show with code R in box 13 the total amount of contributions made through the partnership and with code A in box 14 your Net Earnings (Loss) From Self-Employment.  In the follow-up to entering the box 13 code R amount, enter in the Payments to 401K (non-Roth plan) box the portion at was elective deferral and in the Employer Matching Contribution to 401K box the portion that was the profit-sharing contribution.  

If the retirement contributions are reported incorrectly on the K-1, contact the preparer of the K-1 to obtain a correction.  Otherwise, you can make entries directly in the Self-employed retirement section of TurboTax provided that your Schedule K-1 (Form 1065) shows with code A in box 14 the correct amount of net earnings from self-employment.
