My tax return was filed and accepted. Now I receive W2C (corrected box 16,17). Should I go edit box 16,17 from the current W2 or add new W2 and delete the old one?

Once you start the amendment process you will return to the entered W-2 and only correct the boxes that changed ... do NOT remove the original entry.

No, you will not add another W-2.  If you do, you will duplicate income from that one employer.

You will need to use the Amend Your Return link when you log in to TurboTax to make the changes.
