I also had problems with Sage's gfortran package with OS X Catalina. I instead installed homebrew (https://brew.sh), and used homebrew to install their gcc package. This should install gfortran, which Sage will find as part of its configure process, thereby bypassing Sage's gfortran package. One benefit: Sage will never try to install gfortran again, which saves a good chunk of time. (Installing homebrew's gcc will also create /usr/local/bin/gcc-9.2.0 but not /usr/local/bin/gcc. It is important not to have /usr/local/bin/gcc, since Sage wants to use the pre-existing /usr/bin/gcc.)
