After you file

I believe you might be talking about excess social security that may have been withheld by your employer.  If so, you're not obligated to pursue a refund of the excess amount, if you don't want to.

 

However, please see the TurboTax Help article Can I get a refund for excess Social Security tax withheld? for more information about what your options are.

 

If you're referring to something else, please re-post, if you feel so inclined.
