I'm 64 retired married spouse 65 on Medicare and I'm on ACA. My premium is $8/month. We live on social security alone. I have 401k with a substantial amount in it. My dilemma is if I use it my insurance premium goes up and my social security goes back to the government in tax. My question is how much can I take out of my 401k without getting crushed with penalties and taxes. Our combined social security is approximately $44k. Can I take some money out of my 401k in 2023 or 2024?
