Larger echoes that "seem" to be attached to the bottom are usually structure ...
Suspended echoes are fish ...

^^^ Try this. ^^^ It's not for Garmin, it will however help you.
Rickie posted a link a while back, I'll see if I can find it.
Try typing in, "how to understand downscan or sides can sonar". It doesn't necessarily matter who's brand your watching a video for, the basic concept is the same.
Look on bassboatcentral.com. theirs sub-forum for Garmin sonar, and sonar interpretation.
