The audit check says Your chance of an audit is very low. Your return has very few triggers that auditors usually look for. What are these few triggers so I may fix them

After I entered money that we made from garage sales, house work, handyman work, etc. it now says that I have a few triggers that auditors look for yet my auditing chance is very low. I would like there to be no triggers or at least be informed of what they are so that I am not messing up on the form somehow. So what are these few triggers?
