I have W2 and try to apply the China-US tax treaty to my tax return with Turbotax Deluxe. Do you know where I should enter the treaty-exempt amount? Thanks!

According to previous posted answers, the treaty-exempt amount can be entered as a negative amount under "Federal Taxes / Less Common Income / Miscellaneous Income 1099A, 1099C / Other Reportable  Income”. Unfortunately, I can not find such options under “Federal Taxes”. Please let me know if you have addressed the similar issue. Thanks!
