You should report both W-2s as though they were a continuation of the same form.
If the income on each represents your total income for the year, then you were given two forms because there wasn't enough space to report all the state and local tax on a single form. You will have one W-2 to report in TurboTax, but you will need to keep adding lines to your W-2 until you have included all the state and local tax that was withheld.
See the screenshot below.
