Question about effect of self-employed earnings on bankruptcy

On the budget I originally prepared from this forum and from Business Debtline, I included my current monthly total from self employment which is -£48 and this was deducted from my total income amount. However when I came to fill in the bankruptcy application online, it asked me to enter the amount from my last tax return which was a loss of -£38 per month.

Then in my interview I was surprised when the OR said the loss from my self-employment couldn't be offset against the total income, which meant my total income was higher than I had originally shown. It still showed a minus figure though, so I haven't been given an IPA/IPO.

In the interview I asked the OR about submitting my tax return in January for 2017-18 and what effect this would have on my bankruptcy, but she just said 'submit it as normal'. Can anyone tell me if this is likely to trigger an IPA/IPO if I am showing a profit, or what other effect it could have? My self-employed income in 2017-18 was higher than normal (basically because I was technically supposed to be an employee at a previous job but it took them ages to get me put on the payroll).
