Check boxes 3 & 4 on your W2. Box 4 should be 6.2% of box 3 up to a max of $7,960.80. So take the amount in box 3 and multiply it by .062. If box 4 is more than that you need to get a corrected W2 from your employer. But also go back and double check your W2 entries, you may have entered box 3 & 4 wrong. A lot of people who have asked this found they did enter an amount wrong.
A sure way to fix this is to delete the W2 and re-enter it. That may clear something out.
Box 4 should be 0.062 (6.2%) of box 3, and not more than $7,960.80.
However, Turbotax may round up instead of rounding down. If box 4 says $7,960.80, that may come across as $7961 and cause an error. Or, another customer recently had a more modest income with about $2700 in social security tax. The number in box 4 was something like "2750.51" which Turbotax rounded up to "2751" which then triggered an error as being $1 over.
I think you can file without fixing the error, just ignore it? If the program won't let you e-file, try taking the cents off the box 4 amount and see if that clears the error. I doubt the IRS will care if your W-2 says $2750.51 and you enter 2750.00.
