The calculation was carried out on four <math><mrow><mn>2</mn><mo>+</mo><mn>1</mn><mo>+</mo><mn>1</mn></mrow></math> flavor highly improved staggered quark (HISQ) ensembles generated by the MILC Collaboration. Wilson-clover quarks were used to construct correlation functions. This clover-on-HISQ formulation is not fully <math><mi>O</mi><mo>(</mo><mi>a</mi><mo>)</mo></math> improved, and gives rise to additional systematics over and above those due to removing excited state contributions to getting ground-state matrix elements, and the final chiral and continuum extrapolations to get the physical result. We use the nonsinglet axial Ward identity (AWI) including corrections up to <math><mrow><mi>O</mi><mo>(</mo><mi>a</mi><mo>)</mo></mrow></math> to show how to control the power-divergent mixing of the isovector qcEDM operator with the lower-dimensional pseudoscalar operator. The residual corrections are observed to give rise to <math><mi>O</mi><mo>(</mo><mn>25</mn><mo>%</mo><mo>)</mo></math> violations in relations arising from the AWI. We devise three methods attempting to control the resulting uncertainty in the <math><mi>C</mi><mi>P</mi></math>-violating form factor; each of these, however, can have large <math><mi>O</mi><mo>(</mo><msup><mi>a</mi><mn>2</mn></msup><mo>)</mo></math> corrections. Preliminary results for the nEDM due to qcEDM are presented choosing the method giving the most uniform behavior."
