How does TT handle the $3K capital loss limit over each tax year?

Hello community.  I have been using TT for doing my 78-year old mother's taxes since 2019.  Each year she's had capital short-term losses over $20K each year in her investments.  This has allowed her to take the $3K deduction allowed annually on her taxes.  QUESTION: Is there any way to get a deduction beyond the $3K annually for prior years since she's had more than $3K in losses each year?
