Bug: "Schedule D AMT" missing and TurboTax 2022 "imports" numbers out of thin air

I think I found a bug in how TurboTax 2022 imports data from TurboTax 2021.  TurboTax 2022 seems to be pulling numbers out of thin air, instead of pulling them from a "Schedule D AMT" as expected.  Here's the details:

 

1. Select "Wages and Income"

2. Select "Capital Loss Carryover" in the "Investment Income" section

3. "Do you know your capital loss carryover amounts?" > "Yes, I'll review the amounts...Recommended based on the info we transferred from your 2021 return."

4. "Let's get some info from your 2021 tax return."  I confirmed that all numbers shown on this screen are correct by comparing against the referenced lines on my 2021 tax return.

 5.  Click Continue.  See the "We need some info from the 2021 Schedule D you used for AMT" screen, shown below:

Now I try to check the first two numbers on this screen (Adjusted Short-Term... and Adjusted Long-Term...).  I have no idea where they are coming from.  My 2021 tax return PDF (generated by TT 2021) does not have a second Schedule D adjusted for AMT.  Further, I tried looking in the forms view in the TT 2021 app.  There's a single "Schedule D" -- the one that is NOT adjusted for AMT.  Further, the number imported into the Long-Term box DOES NOT appear anywhere in my 2021 tax return PDF!

Where on earth is this number coming from?

 

It seems to me that at least one of the following is true

 

(a) TurboTax 2021 should have generated a "Schedule D AMT".  Even if this is not included in the return PDF, it should be included in the forms view of the app, since it is used as part of the computation.

(b) TurboTax 2022 is pulling a number out of thin air to fill in the box.

 

I tried searching the forum in case someone else already found a solution to this problem.  The closest I can find is this thread from the 2017/2018 tax years.  On that thread, the author followed up to say that they later found the "Schedule D AMT" in the forms list at the end.  That's definitely not the case for me.  I've sifted through the forms list half a dozen times now, and there's definitely no AMT version of the Schedule D in there.

 

Anyone got advice? How can I report this to Intuit as a bug?
