@Opus 17 while the "three year window" to file a 2019 tax return to claim any refunds is July 15, 2023, the deadline to amend a 2019 tax return to claim any refunds is the earlier of a) three years after the original date the tax return was filed or July 15, 2023 (assuming no approved extensions), which ever is earlier. So for many that already filed, the three year window to submit an amendment has expired 😒
it's an interesting nuance I recently learned.
