Retirement tax questions

Thank you for the response. 

 

No, I don't have foreign-earned income or 401(k). So I only need to look at Schedule 1 line 3 minus Schedule 1 line 15 and I can ignore line 10 which total appears as "Other income" on Form 1040 line 8, correct?

The reason I ask this is (1) I had a loss on the rental estate (line 5) and the total on line 10 sums up a lot less. (2) I just worry about the wording "other income" on 1040 since I'm stuck on TurboTax which says this is not earned income and my net income is zero.
