Edit capital loss carryover worksheet

That would be your short term capital loss. You would have to amend your 2021 return to correct that. It is possible that it won't affect your tax if you had capital losses of over $3,000, as that is the most you can deduct against ordinary income in a year. If not you should amend the return anyways to set the record straight.

If you need to amend your return, you will see an option to do that on your home page when you log into TurboTax. Look at the bottom of the page, under Your Tax Return and Documents. Click on the year you want to amend and choose the Amend (Change) option.
