Is NOBODY wrong in the post ? POST : Weird title I know but bear with me for a sec.
Some info on the situation: I'm 20 now, still live with parents but I pay half of the expenses that are mine and have no problem with that. The problem comes up when my parents still try to force me to do all the cleaning, I was forced as a teen to do this because I wasn't working a 9 to 5 job but now that I do and pay for my share of the apartment I proposed that we split the task.

Not a good idea apparently since they looked at me like I fucking killed out cat which lead to them cussing me out saying that I don't appreciate what they do for me despite me pointing out that I pay half of the expenses sometimes even the full amount when they can't cover it and constantly do the shopping and cooking

Tl;DR parents want me to still clean the house as my responsibility despite me working 9 to 5 like them and paying half of the living expenses
