@fanfare, Thanks for the quick response. Unfortunately, Turbo Tax determined Schedule D wasn't required in my case and checked the appropriate box on the return. I checked my 2022 taxes and the same is true, so I don't have a Schedule D to compare with my 1099-B from the broker.
I've thought of going through entry of the whole capital gains section again just to see what it asks me, but I don't want to change or overwrite the file from what was originally filed. I guess I could just start a new 2021 for a dummy person and just go to that section. But since it says you can enter aggregate or individual transaction data, that still wouldn't allow me to see what I did before.
This seems to be a major flaw in how Turbo Tax does things -- a user needs to be able to get back to their entries and follow the trail they originally followed in case of an IRS query or error notice. This is definitely giving me pause about continuing to do my own taxes, although they really aren't that complex and I've enjoyed using Turbo Tax over the past 15 years or so. But I have no way to determine whether the IRS is correct (and whether I made the same mistake in 2022).
I would appreciate any ideas on how I can see the data under the covers. It's my data and I entered it, so it should be able to give it back to me.
