If I have a W2 and a 1042-s code 16, how do I file that in Turbo Tax Deluxe?

I already filed the information from my W-2 and I filed the income listed on my 1042-S following these steps:

1. Select the "Federal" tab in the black navigation bar on the left
2. Select "Income & Expenses"
3. Select "Add more income" button if necessary
4. Scroll and click "See the list of all income" 
5. Scroll to "Less Common Income" and select "show more"
6. Select "Miscellaneous Income"
7. Scroll and select "Other Reportable Income"
8. Click "yes" then enter the description and amount

However, I cannot find where to enter in the federal tax withheld in Box 7a and 10 on my 1042-S to make sure I don't get taxed twice. 

Thanks!
