Won't let me file until I fix Box 12. It keeps reporting that the amount in Box 12 should not be greater than the value in box 12 with code S but it's the same amount.

If you have only one entry for box 12 make sure you have only made one entry ... I suggest you delete the W-2 and enter it again manually if you cannot seem to fix the issue.

This issue is being worked on. Check back in a week. 

it has been a week since the original post.  is there an update.  I am also having the same issue and this is stopping me from filing my taxes.  

You can try to remove the cents in the box on the 'Check this Entry' screen. This should remove the error message.

Why is W-2 Box 12 code S causing an erroneous "Check this Entry" error message?

I did 2 things.

I manually entered my W-2 but that also created the same issue.

The 2nd thing I did was reduce the cents value by 1 until it took it.

The original value was 09 cents, but it finally took it after reducing the cents to 05.

Seems like a weird issue, but that's what worked for me.

Hope this helps.
