If your dates are correct, you need to amend your 2021 return.
Turbotax online is working the 2022 season. To amend a 2021 return that was filed using the desktop software, you can open the software and click Amend from the list of things to do. If you filed online, I believe you log in, navigate to your 2021 return, select Amend, and follow the instructions. (I can't find a working live link in the forum for 2021, I don't know why.)
If you really meant 2022, for the tax return you filed in 2023 (this month), the amending function will likely be turned on in mid-March.
