I just checked my return in turbotax 2020 which was a CD not a download and it was the deluxe version as well and the same thing happened last year. The prior year depreciation numbers didn't flow to the asset worksheet. But it wasn't the final year of tax depreciation so it didn't cause an issue. It only causes a problem in the last year it looks like. I suspect if I look backwards I will find it never worked. I never remember it flowing in. I just loaded the 2009 premier edition and same issue. the prior depreciation and amt depreciation don't flow in! So old bug never fixed. Possibly never reported.
Initially when I looked at the schedul the calculation was right, but when I went to the page again I suddenly noticed my return went from a small refund to a huge payment and when I tracked it down it was on the tax AMT calculation and I then went back through the calculations and found that the AMT adjustment was 165,000 instead of 1850. So I went to this schedule and found the AMT variance was the full house basis...
So I still think the bug is only noticeable in the final asset year. It is a bug in all years, but only affects the final.
