Capital Loss carryover over two years

I am using TT to do my tax. 

Need help with the above and could understand how TT compute it.

I have a $13,810 loss carryover from 2023;  2024 I have another loss of $10,207.  Shouldn't I have $6,207 left after $3,000 deduction this year.  The total carryover to 2025 should be $20,017? But TT said my 

carryover is $16,838.
