Are you sure you deleted any previous entries? The steps I gave you will not replace or remove a previous entry of the same 1099-MISC.
Does the $250 appear on Form 1040 line 21?
Does the $250 appear on Form 1040 line 12? If not, what do you mean by "a business item entry"?
If it appears on both lines 12 and 21, there is a previous entry that you have not deleted.
If it does not appear on line 21, go through the steps again and make sure you answered the questions exactly as I said.
