In order to be asked the question "Do you know your capital loss carryover amounts?" you had to first answer Yes to the question "Did you have investment losses you couldn't claim in 2019?" But if you didn't have a Schedule D for 2019 you didn't have any investment losses in 2019. So you should have answered No when it asked "Did you have investment losses you couldn't claim in 2019?" If you answer No to that question, it will not ask any questions about a capital loss carryover or your 2019 Schedule D.

You can get back to the question about investment losses in 2019 by typing "capital loss carryover" (without the quotes) in the Search box, then clicking the link that says "Jump to capital loss carryover."

Hey, I am on the same boat, I found this question right before I submit the identical one; when you said "You can get back to the question about investment losses in 2019 by typing 'capital loss carryover' (without the quotes) in the Search box, then clicking the link that says 'Jump to capital loss carryover.'" - When I do that, it just takes me back to the same question "Do you know your capital loss carryover amounts". What do I do?
