See the section on using oneTBB with Stan Math: https://github.com/stan-dev/math#intel-tbb

The above section explains how to install oneTBB. I have it installed.
But tests still fail with version 4.4.0

Can you try cleaning and rebuilding the math library dependencies/objects and posting any errors you encounter?

cd path/to/stan-math
make -f make/standalone math-clean
make -j4 -f make/standalone math-libs
