Yes, you can file an amended return for 2022 Tax Year with the 4852 form and revised 1040. Note that there is some risk of getting audited if you file an amended return, but it may be worth it if the refund is huge and it gives you additional resources to fight off the IRS if they decide to attack.
I think you can go back 5 years to file amended returns and collect back taxes paid, but I am still figuring out the specifics. It appears to be a rolling 5 year window that expires each October 15, so the deadline for 2017 may be October 15, 2023. You can confirm from IRS website if you do a search on "amended return".
