@Kawh sorry for resurrecting this old thread, but could you clarify which one you did?
1. Manually change Schedule 3 Line 11 - added the excess social security amount and file via paper (NOT e-file)
... OR...
2. Change your W2 (I am not sure how and what you did here since W2 form cannot be changed), manually change Schedule 3 Line 11 and then file via paper (NOT e-file)
