Where is Turbotax getting the numbers I see on the Sched E/passive activity worksheet?

I'm using the desktop version not online. When it did the 'check for errors' it wanted me to add some entries in a worksheet but I think I messed them up some entries for prior years and I can't figure out how to fix it without starting completely over. I have all my records from TurboTax going back to 2018 but I don't know where the system is pulling the numbers from to know what to fix. In at least one year we did have QBI income for our vacation rental but most years have been losses.  worksheet section

Form 8582 figures the amount of Passive Activity Loss (PAL) for the current year and reports the application of prior year of prior year unallowed PALs.  As a result, all unallowed PALs are listed on Form 8582.  The form shows the prior year unallowed PAL that carried forward, the allowed loss, and the unallowed loss, which carries forward to the next year on Form 8582.  The numbers you are seeing on the Schedule E worksheet should have come from Form 8582, Part VII, Allocation of Unallowed Losses.
