I need to know how to amend my 2023 and 2024 tax returns through free tax USA from married filing separately to married filing jointly as I did it wrong those two years. I did not file through free tax USA. I need to know the steps and process because it's honestly super confusing. I'm not sure if I just file the way I meant for Those years emmediatly or file it exactly how I did last time and then how I need it now. It's super confusing please someone help.
