Can't determine why intelliJ is moving my comment to a new line

I have save action and code format enabled, so I understand literally why the line is moving. It's because I have auto-format enable and it is auto-formatting the code. 

Yet, I have no idea how to tell the IDE "please, stop doing this!"

The example is simple, I have a mapstruct mapping, and I want to put a comment after it (not above, not below)

@Mapping(target = "whatever", ignore = true) // TODO discuss how to implement Whatever
Target toTarget(Source s);

This is how I would like it to look, below is how the auto correct messes it up:

@Mapping(target = "whatever", ignore = true)
    // TODO discuss how to implement Whatever
Target toTarget(Source s);

I have wrapping at 120, but this only reaches 91 characters. So it's not that.

I have no idea what other setting would force this.
