T5013 Partnership Income box 005. My % is 0.000017 but Turbo reports and error of too many digits. A previous answer to this same question on the forum was too vague.

If you box 5 figure is more than 2 decimal places, you would generally round it to 2 decimal places. In your case, this would result in .00. This box is used only for data purposes and not used in any calculation so it's fine to list it as.00 or leave it blank.
