The rule in plain words

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

What to do if your return fails it

1. 01Open the table below and find the cells the rule reads.
2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
3. 03It runs only when your filing indicators mark OF21.00.01 as reported.
4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
