I had a HDHP (family plan) through my employer up until August 2023. I retired and my spouse and I moved to Medicare Part B on August 1. We are both over 65. Based on TT calculation we have a HSA limit of $5104. I assume that is for 2023. Can I contribute that amount into my HSA now and claim it as a deduction for 2023? If how do I do that? Thanks.
