Hello Weridelong,
Thank you for participating in our Ask the Expert event today. As to your question, if you used TurboTax for both of those years it would automatically carry it over from 2020 to 2021.
Whether you did or did not use TurboTax, you can look at your 2021 Schedule D, line 6 (short-term) or line 14 (long-term) to make sure it was carried over.
