Retirement tax questions

Hello I am in the exact same position except for tax year 2017. I did withdraw the excess contribution via Vanguard prior to filing my taxes as recommended. I had excess earnings of only $46. I asked Vanguard to withhold 10% federal tax on this amount. How do I report these earnings? I am using TurboTax Home and Business; the SEP IRA is showing up under business, but I don't see a place to report excess earnings.
