If I withdrew only my contributions from my roth IRA, why are some of it saying it's retirement income when I added my 1099-R info? None of what I withdrew were earnings.

So for example, if I contributed 18k within 5 years to my roth IRA accounts, and I only withdrew 15,900 I should not be having penalties or owe any taxes. How do I tell Turbotax that when I am filing my taxes?
