You do not enter your daughter's W-2 income on your tax return. She files her own tax return and enters the W-2 income. When you prepares her return, she must indicate on her return that she can be claimed by someone else.
Depending on how much income she had, she may not actually be required to file a tax return. The standard deduction for a person filing as Single is $12,200 so she could make up to that amount before having to file a tax return. However, if she had federal income tax withheld, she should go ahead and file a tax return to get a refund even if she isn't required to file it.
