Opting out of deferral of one-half of social security portion of SE Tax

[earl_garrison]

How do I "opt out of" the deferral of 1/2 of the social security portion of the SE tax?

Ive just ben putting a zero in Line 18 of the Sch SE where it asks for the wages.

Im not sure if that's technically correct, but it seems to get the job done, no rejections.
