I did see and did read your post and I know the IRS "take" on this. I, honestly, am just baffled now as to what is causing this error message for you still.
This is what the IRS site states:
"To claim a refund of Social Security and Medicare taxes, you will need to complete and submit IRS Form 843. When you apply for a refund from the IRS, include either: A letter from your employer stating how much you were reimbursed. Or, if you were not, a copy of your W2s that show the amounts withheld in total"
The only thing I can figure to do in order for you to have this flow properly within TurboTax is to adjust the amount to the maximum, and submit to the IRS AND SSA copies of your W2's along with a letter of explanation as to what you E-filed with TurboTax. Remember, please, that the IRS and SSA already have this information from your employer as your employer had to submit a W3 for themselves, along with copies of every single W2 for each of their employees (obviously, the payroll processing firm does this, but same thing). You, personally, sending this via USPS Certified Mail / Return Receipt Requested is doing your due diligence along with applying for a refund from the IRS. This way, BOTH parties (IRS and SSA) are on the same page. I have seen many people do this in past. Again, the decision is obviously up to you. I just wanted to provide you with instruction on a viable option.
