I was an LLC - partnership filer last year, and it looks like Turbotax helpfully converted all my stuff over for this year, however I elected s-corp status for 2022. I cannot find a place to change that, and after filling everything out, my 2022 return is still a form 1065 not a1120-s.
It might not be what you want to hear, but you need to start an initial (new) 1120-S in TurboTax Business (i.e., start from scratch as an S corporation).
There is no way to transfer a 1065 to an 1120-S in the program.
You have to start over from scratch and select S-Corp as the type of business. So you will be filing your very fist 1120-S. Take note also that you can not import data from your prior year 1065, into the current year 1120-S. You'll be dealing with all that stuff manually.
