So sorry for your loss. For the year that your spouse passed away you could file a joint tax return. But for 2024, unless you have a qualified dependent to claim, your filing status changes to Single. It is best to start a new account with a new user ID. It is too difficult to delete the embedded information from a spouse if you use the same account that was used for past joint returns.
Sorry for your loss. I lost my husband in 2023 too.
You can file a Joint return as normal the year your spouse died. For the next two years following a husband's or wife's death, the surviving spouse can file as a qualifying widow or widower if they have a qualifying child. That basically lets you continue to use the same tax brackets that apply to married-filing-jointly returns. After the year of death if you don't have a child you file as Single.
For 2024 you need to start over with a new return and new account. And don't transfer from 2023. You can't delete a spouse especially if he was listed first.
