Here's an FAQ with instructions for amending returns that you filed with TurboTax. (The title says "prior year" but it also works for 2022.)
How do I amend my federal tax return for a prior year?
Before you start to amend your return in TurboTax Online, be sure to download a PDF of your original tax return and save it on your own computer. Once you amend it, you will no longer be able to access the original in TurboTax.
Amended returns for prior years cannot be e-filed. You will have to print the amended returns, sign them, and file them by mail. Mail each year in a separate envelope, and send them by certified mail with a return receipt so that you have tracking and confirmation of delivery.
