What "Schedule X" box to check?

[lameri]

Hello,

I need to amend my 2019 tax return. The reason is that the software had a bug that calculated depreciation incorrectly. The only way out of it (with the help of a Turbotax CPA on the phone) was to edit even the labeling, then it got the expected numbers. I noticed because my 2020 numbers were different for no reason (the depreciation was the same, no upping of the basis). In sum, since I was filing my 2020 taxes, that is what I focused on, but the Turbotax CPA told me I would need to amend the 2019.

Do I check "error on original return"? It was not my error, but from the list, it is the one that matches it better.

Thanks!

That question is just a TurboTax survey for why people are amending.  Your answer does not go to the IRS.  Check whichever answer is closest to your reason for amending.
