The sole employee's SEP contribution is not to be reported in the Traditional and Roth IRA section.
It is also not reportable on Schedule C even though it is based on the net profit reported on Schedule C. The deduction is taken on Schedule 1 as a self-employed retirement deduction, calculated on TurboTax's Keogh, SEP and SIMPLE Contribution Worksheet. The entries for this worksheet are made under Other Business Expense -> Self-employed Retirement.
