Sorry for your loss. My husband passed in 2023. You need to start over and set up a new account for yourself and not transfer from last year. You will have to re enter any prior carryovers and depreciation, etc. manually.

TurboTax will not allow you to remove the primary taxpayer on the return. And you should not try to change the order of names. If you were listed as the spouse and want to be the primary taxpayer now or delete the primary person, you will need to start a new return by logging out and starting over with a new account and new user name and password. You will not be able to transfer from the prior year.
