Just use one RUN command, and escape newlines. If you have several commands, you have to wrap them in a bash command.

Besides that, you can extract from a .tar.gz file directly without uncompressing it first.

FROM amazonlinux:latest 
ADD . /tmp/ 
RUN yum install gzip -y && \ 
    yum install tar -y && \ 
    yum install libstdc++.so.6 -y && \
    /bin/bash -c 'cd /tmp && \
    /usr/bin/tar -xzvf TeradataToolsAndUtilitiesBase__linux_indep.16.20.10.00.tar.gz && \
    cd /tmp/TeradataToolsAndUtilitiesBase/ && \
    ./setup.bat a 
CMD ["/bin/bash"]
