It's not clear if the W-2 amount is duplicated on the 099-Misc or you'r just saying part was reported on a W-2 amd part on the 1099-misc.
If the latter, just enter the W-2 and 1099-misc, separately at their different entry places in TurboTax. The withholding on the W-2 will eventually be applied to your total income.
