It looks, as if the first 12 plies of Yace are not too bad.
But - is your line correct? It is late at night here - so I might seem stupid.
However, following your line until 18.e7, I cannot see a mate in one after
18...Kb8
26 0.868 -Mat11 16. 18...Kb8 19.e8=Q+ Kc7 20.Qg6 Kd7 21.Kf7 g1=Q
22.Qxg1 Kc6 23.Qd4 Kb5 24.Ke7 Kxa6 25.Qb2 Ka5
26.Kd6 Ka4 27.Kc5 a6 28.Qb4# {-921}
OTOH, slightly earlier in your line, Yace sees
496 1.891 Mat05 62. 16.Kd6 Kb8 17.e7 Be5+ 18.Kd7 Ka8 19.e8=Q+ Bb8
20.Qe4# {651}
instead of 16. f8Q+.
Again, as black's 15th move, Yace suggests:
33 0.844 -Mat10 17. 15...Kb8 16.Kd7 Bf8 17.e7 Bxe7 18.Kxe7 Kc7
19.f8=Q Kc6 20.Ke6 g3 21.Qd6+ Kb5 22.Kd5 g2
23.Qc5+ Kxa6 24.Kc6 g1=Q 25.Qb5# {80}
