Get your taxes done using TurboTax

Use her correct SSN; you have to file a prior year return by mail anyway.   Is her correct SSN on the W-2c?   You can use the amounts from the original but tell TurboTax it is a corrected form W-2 on the uncommon situations screen.  

See IRS Q&A if her w-2c still has the wrong SSN -  If needed, you can file Form 4852 by checking the Didn't get a w-2 box right below the corrected box.
