Did the IRS say you claim excess social security? That's because you entered all the W2s under one name. The IRS is usually right in these cases so just pay the bill. Then check your 2015 return and see if it happened again. Excess SS is on 1040 line 71 so check there. Then for 2016 next year do not transfer from 2015 or delete any W2s and re-enter them manually again.
