How do I enter a capital loss carryover from 2022 on my 2024 return? Turbo tax defaults 2023. I did not use Turbo Tax in 2022.

You need to figure out what the carryover from 2023 would be.  You can’t skip a year.  Did you include the loss from 2022 on your 2023 return?

You have to report the carryover every year until it's used up.  You can't skip a year.  Even if you don't report it on your return you have to reduce it by the 3,000 (1,500 MFS) when you carry it over to next year.  You can't choose when to use it.

This is from the IRS Pub 550 page 66 Capital Loss Carryover

"When you figure the amount of any capital loss carryover to the next year, you must take the current year's allowable deduction into account, whether or not you claimed it and whether or not you filed a return for the current year. "

Here is pub 550…  http://www.irs.gov/pub/irs-pdf/p550.pdf

You might want to amend the last 3 years to include it.
