Can I Retroactively Claim Head of Household Status and Dependents on Past Tax Returns?

This year I filed my taxes as head of household because my mom doesn't work and has no source of income; I cover practically 100% of her expenses. Last year, in 2023, I did my 2022 taxes but I didn't claim her as a dependent, even though in 2022 she was entirely my responsibility. Is it possible to make any corrections to that tax return I filed in 2023 for the year 2022? Can I get any money back through a correction? Thank you.
