I work a job where I'm overseas a lot and missed a few years of filing. I always get a return so I was expecting I'd just get five years worth of returns when I finally filed. I've since learned that's not the case. It was my understanding that I forfeited my refund from 2021 but that 2022 should be received as long as I filed prior to April 15th of this year. I filed all of my back taxes and 2025 taxes on March 18th of this year. I received my 2025 refund pretty quickly and I received my 2023 and 2024 refund about a week ago on the same day. I've yet to receive my 2022 refund. Was I wrong about the time cutoff for the 2022 return? Did the refund need to be sent by the IRS to me by April 15 of this year or did the return just need to be filed by then? I can't get a live person to talk to from the IRS and the automated system only goes back to 2023. At this point I'm fully prepared to accept losing the return it's just a curiosity currently. Everything I've read says I should have gotten it. Any insight or knowledge is appreciated.
