Start a new turbo tax account if filing separately

Hi, do I need to start a new turbo tax account if both my spouse and I file married file separately in 2021? In 2020 and prior, both my spouse and I file jointly. We used turbo tax online account. In 2021, I plan to file head of household and my spouse will file married file separately. I'm using the existing turbo tax account. My spouse has created another turbo tax account. The existing account has his name as the first tax payer and my name as second. So I changed the account to my name and enter my name as the first tax payer. However, the software kept asking something about my spouse's. But what it asked is really related to me, such as self employment income. I guess the software is confused about the switch between the first and second tax payer. I have basically the same info such as children and carry over info of rental and depreciation from prior year. It will be much easier to use the same account. How to let the software know that there is a switch between the tax payer? Or do I need to start a new account?
