Hi For "Who you are preparing this return for? I cannot change my selection from "Myself" to "My souse/partner and me" Please advise how I can I revert my selection?

If you are using TurboTax Online, once you start your return after choosing "Myself", there is no way to add your spouse/partner. You would need to start a new return if you want to prepare your return together with your spouse/partner.
