You cannot report your daughter's W-2 income on your tax return. Her W-2 goes on her own tax return, if she files one. If her income is low enough, she may not be required to file. But if income tax was withheld from her pay, she might want to file, even if she is not required to, to get a refund of the income tax that was withheld. (Only income tax can be refunded, not Social Security or Medicare taxes.) If she is not required to file, and does not file, her W-2 does not have to be reported anywhere.
In TurboTax Online each user ID can file only one tax return. If you need to file a tax return for your daughter, you cannot use the same user ID that you used for your own tax return. You have to use a different user ID.
