This "current" TLE set is actually the last TLE set for JWST that was published on December 28, 2021. It can only be used for tracking JWST when it was less than about 50000 km from Earth. TLEs and tracking programs that use the SGP4/SDP4 model are useless for tracking deep space spacecraft that are more than about 50000 km from our planet. For deep space you need other types of parameters, like state vectors, and other programs, like GMAT.
But, as Joe indicated, several deep space spacecraft, such as JWST, can be tracked online using JPL's Horizons.

Use the NASA/JPL Horizons system to track JWST and other objects that are not in a "normal" earth orbit. JWST is essentially in solar orbit, perturbed by the Earth. TLE and the underlying "simplified perturbations models" that are used by GPredict and the like don't work for solar orbits.
