Note that the IRS mentions contacting your "tax preparer" -- but if you used TurboTax, you were your own tax preparer. You used "do-it-yourself" tax software. Your Form 1040 shows that your return was Self-Prepared. That means TurboTax has no further information, and cannot intercede with the IRS on your behalf.
You could try contacting an Advocate.
