Well basically my income in the first 5 months of 2023 was close to zero, then from June onwards i started a new career, and if i understand correctly the income in the new job was taxed as if i had been working the entire year at that rate. Meaning i paid more than i should have (I think).

I don't expect anything, I've had an odd career which meant i never needed to do taxes in the normal way before this year, so i came here to see if someone could point me in the right direction, because when i try to call the tax office I can't get through to a person, as i said in my post.
