I made an excess Roth IRA contribution and need to pay tax and penalty on the earnings. I have converted the contribution to a 2018 contribution but need to pay the tax

I made an excess contribution to my Roth IRA of $3000 in 2017.  I have now done paperwork to change that contribution to a 2018 contribution to the same Roth IRA.  I was advised by my broker that I will simply have to pay tax on the income earned by that $3000 (which they have calculated to be $42.30) and I have to pay a penalty on that money as well.I am using TurboTax Deluxe and I have answered all the questions it asks me about this but there is no place for me to put in (or that I can find at least) the $42.30 in income so it can calculate the tax owed and the penalty.  It never asks me in any of the prompts how much I earned, etc.  Can someone help me to navigate the TurboTax part of this and get it to ask me the right questions?  Alternatively, is there a number where I can get someone live on the phone (from TurboTax) to help walk me through this in their software?
