No, the SEP contribution would be entered on his or her business return schedule C entries for sole-proprietorship income. You may need to indicate that she has employees to see the options under Less Common Business situations when she enters her self-employment expenses. You will see an option for Self-employed retirement. Just work through that section and you will see where you can enter her SEP contribution.
If she works for a company and her employer made contributions for her, then the SEP contribution would be listed on the company's tax return and any contributions she made would be subtracted from her wages, so you would not make an entry on your personal tax return.

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.
