Ohhh, I see what you mean, it errors if you put it in that 2A box.

If youre sure they shouldnt get EITC, (see Bills comment above), you can just check one of those other boxes in Part IV, and it will disallow it.  Either of these will do it.....but be prepared for IRS to send the client a letter explaining that they may qualify for EITC, since all IRS sees if that Wages amount in Box 1 of the W2 and that looks like earned income to them..
