I have a 'Capital loss carryover from 2024' (-$X) Turbotax stated 'All capital losses used in 2025' ($Y) Where is $Y come from? Thanks.

Capital Loss Carryover. Where does Turbotax get capital loss data from my input? I did not enter data myself.

You would need to print out the PDF of your tax return and look at Schedule D (if included) to determine exactly what $Y consists of, but it is this possible combination of items: 

A. current year 2025 short-term capital losses from all investment sources
B. carryover short-term capital losses from 2024 and back
C. current year 2025 long-term capital losses from all investment income sources, and 
D. carryover long-term capital losses from 2024 and back 

To print the actual tax return document and determine how your 1040 line 7 net capital gain or loss is computed (including all capital losses used in the current tax year), follow these FAQ instructions, then Ctrl + F search for Schedule D. Anything written as a negative number in (brackets) is part of the total $Y.

your carryover remaining $y comes from offsetting your 2025 gains and losses with $x.

TurboTax knows the calculation. That's what you're paying for.
