Retirement tax questions

Oh - you are correct, your SSN is auto-populated from your personal information so you really do not need to change anything - it is already correct on your return.  The W-2C will be sent to the IRS so that it will match what is on return.   I forgot that your SSN is not something that comes from the W-2 in the TurboTax interview (they do that precisely so you cannot get the wrong SSN entered on the W-2).
