Certainly worth it to me too.
Hopefully you've already (or can now since amending) taken advantage of all possible deductions. Since you said you're a teacher, I'm sure you're aware of the educator deduction? And, since most teachers also provide many of their own supplies, and assuming you're a teacher in a public school, the amounts of your supplies that exceed your $250 educator deduction, could very well be considered a donation to a non-profit organization (the school)? Since the IRS allowed charitable donations in 2020 and 2021 as a separate line item deduction without having to itemize, you were able to maximize that deduction too? Plus, if either the life time learning credit or the tuition & fees deduction, be sure ALL allowable amounts paid are included, and not just the tuition (emphasis on tuition AND FEES).
