business income limitation would be the s-corp income before the 179 deduction and wages also count as business income.
you cannot defer taking 179 if you elect it for a current year addition or it's a carryforward. the only exception to this is a lack of basis or business income. If you override to limit it, the IRS might catch this but it could be a couple of years down the road making subsequent returns incorrect and therefore needing amending.
overrides will prevent e-filing and the voids the Turbotax accuracy guarantee.
