In the past Turbotax had more detailed version tax returns containing backup calcs (more detail than the version submitted to the IRS). where I can find this for 2022?

Sounds like you want to see all the schedules and worksheets.  Those will be part of the pdf of the return when you pay and save the return as a pdf.   With online TurboTax you do not have Forms mode, so you cannot see all the forms and worksheets until later after you have paid your fees and saved the return as a pdf.
