no it was a small business on the side... lasted couple of months...
Did you incorporate?
Hmm... it would be pretty hard to confirm it ever existed then? I doubt they'd call you, since they are trying to confirm what you said in your app.
Most likely they won't try to confirm it, especially if it only lasted a couple months.
I spent multiple years working for myself, several of which were pre-incorporation I wouldn't worry about it.
