Yes, you can still apply the tax treaty to reduce your income.  In the TurboTax program, report your full income. Then you can enter the treaty exempt amount as negative income under "less common income". You will have to file a Form 8833 to claim an exception. As TurboTax does not support Form 8833, you cannot e-file.  Instead, you may use Turbotax to prepare your return, but need to print out your tax forms and mail the returns along with the form 8833.   Besides the Form 8833 and 1040, you will also need to submit a copy of your tax documents ( for example, Form 1099s) which pertain to any credits and deductions you are applying if there are any.
