which sym -all
If Symbolic Math Toolbox is installed, it returns MATLAB_ROOT\toolbox\symbolic\symbolic\@sym\sym.m as of R2021a.

In R2020a, sym points toolbox\symbolic\symbolic\@sym\sym.m, too.
Please confirm you have installed Symbolic Math Toolbox by executing ver command.
ver
If the toolbox is installed, you will find "Symbolic Math Toolbox" in the ver result.
If not, you need to install the toolbox.
