This paper reports a search for a light CP-odd scalar resonance with a mass of 20 GeV to 90 GeV in 13 TeV proton-proton collision data with an integrated luminosity of 140 fb*−*1 collected with the ATLAS detector at the Large Hadron Collider. The analysis assumes the resonance is produced via gluon-gluon fusion and decays into a τ+τ− pair which subsequently decays into a fully leptonic µ*+ν&sub(µ)ν^¯&sub(τ)e*−ν^-eντ or e*+ν&sub(e)ν^-&sub(τ)µ*−ν^-µν&sub(τ) final state. No signifcant excess of events above the predicted Standard Model background is observed. The results are interpreted within a favour-aligned two-Higgs-doublet model, and a modelindependent cross-section interpretation is also given. Upper limits at 95% confdence level between 3.0 pb and 68 pb are set on the cross-section for producing a CP-odd Higgs boson that decays into a τ*+τ*− pair.
