But my W2C form only contains information that was incorrectly reported previously. Actually this is the main reason why I am confused about what to do. Does turbotax e-filing submit the uploaded W2 and/or W2C together with my tax returns to IRS/state tax agencies or does it only read information from them but not actually submit them? In the latter case, maybe I can let turbotax read the W2 form and then manually correct the boxes on turbotax that are corrected by the W2C (if I only upload the W2C instead, turbotax won't be able to find all the information needed)? If @ee-ea or anyone else could clarify this, I would appreciate it.
