Get your taxes done using TurboTax

Hello I also have a question about line 17 on form 8379. Line 17 ask for your credits minis any earned income credits. If you go by the guide it tells you take the credits from line 13a of your 1040 or from schedule 3. I added my child tax credits and my retirement contributions credits. What about additional child tax credits? Do I add that number in too? If so were is that exact amount shown? Please help!
