tbb::atomic class (as well as multiple obsolete and compatibility features) was deprecated in TBB 2019 U9 (for more information see TBB Revamp topic). All of these features were removed in oneTBB 2021.

Consider using std::atomic as a replacement for tbb::atomic.

tbb::atomic was introduced when C++11 atomics were not invented yet. However, with C++11 tbb::atomic became obsolete and did not bring any value. Overall, C++11 atomics can be more efficient than tbb::atomic because they are recognizable by modern compilers and some additional optimization might take place.
