This talk presents results, based on the papers
arXiv:2201.07114 [hep-ph], arXiv:2109.12051 [hep-ph],
Phys. Lett. B 806 (2020) 135478 [arXiv:2002:12810 [hep-ph]],
on the determination of the TMD parton distributions and
rapidity evolution kernel from transverse momentum spectra. It
is shown that the bias induced by PDF in TMD extractions
is alleviated if PDF uncertainties are taken into account and
the TMD profile is flavor-dependent. Both points improve the
agreement between theory and experiment, substantially
increase the uncertainty in extracted TMD distributions, and
should be taken into account in future global analyses.
