Make sure that you are entering the Schedule K-1 in step-by-step mode, not in forms mode of the CD/download version of TurboTax. Upon entering the Schedule K-1 (Form 1065) box 13 code R amount, TurboTax will prompt you to divide the amount between employee elective deferrals, Roth contributions and employer contributions. Do not enter these amounts separately in the self-employed retirement section of TurboTax.
If the sum of the employee elective deferrals and Roth contributions exceed the statutory limit, TurboTax will flag an error on line 6a even though line 6a is not where these contributions should appear.
