Other Income on CT600

Hi,
I'm trying to complete my final micro accounts & corporation tax online using HMRC's system, however I have other income that I need populated in box 205 on the CT600 but I cannot find where to input this using the online system.
After calling HMRC they can't advise me on where to put it (which seems ridiculous, as it's their system & their form),
does anybody know where in the online input system I have to put this so that it appears in box 205?
Thanks!
