In line 18 and 19, I have two dollar amounts do I need to add those amounts together. Do I add whats in 18 together and enter on the sheet for 18 and the same for 19?

Please clarify your question by adding some additional information so we may better help you.  Such as: What version of TurboTax are you using? What form are you asking about? What sheet are you adding the amounts to? What TurboTax screen are you on? Are you getting an error message?
