Last week, I received a refund for a medical procedure that I had paid through an HSA. This had come up a couple of times before, and I merely returned it to the HSA as a return of a previous withdrawal (there was a form to fill out, or something). This time, it's a bit more complicated--the HSA from which the funds were drawn no longer exists, and the procedure was performed in 2017! How do I submit it as a return of a previous withdrawal if it wasn't taken from my current HSA? Am I just stuck declaring it as income? It's certainly not going to fall within the correct calendar year. Any suggestions? Thank you in advance.
