The word 'Quatsch' (nonsense) is used mainly in informal spoken language. In formal or written contexts, it often seems inappropriate.
Ach, das ist doch alles Quatsch, was er da erzählt.
Oh, that's all nonsense, what he's saying there.
The word 'Quatsch' (nonsense) is used almost exclusively in the singular, even when talking about a lot of nonsense. A plural form practically does not exist.
Hör auf mit dem Quatsch und sei still!
Stop with that nonsense and be quiet!
The combination 'Quatsch machen' (to fool around) is a fixed expression. It means to behave foolishly or get up to mischief, and it is often used in connection with children.

The children fooled around in the garden all afternoon.
As the short exclamation 'Quatsch!' (Nonsense!), the word expresses strong disagreement or disbelief. It usually stands alone, often at the beginning of a sentence.

I'm supposed to get all of that done by tomorrow? Nonsense!
meaning / sense
'der Sinn' and 'der Quatsch' are opposites when it comes to logic, meaning, or purpose. 'Sinn' is used when something is understandable, reasonable, or makes sense. 'Quatsch' is used when something seems stupid, illogical, or false. 'Quatsch' is more colloquial and can sound clearly dismissive. A simple guide is: something that has 'Sinn' can be well justified; something that is 'Quatsch' makes no sense.

Was du da über Anna gehört hast, ist doch völliger Quatsch.
What you heard about Anna is complete nonsense.
Der Sinn der neuen Regel ist, dass alle sicherer arbeiten können.
The purpose of the new rule is to allow everyone to work more safely.
