199A QBI does alimony paid reduce income for qualification?

If I pay pre 2018 deductible alimony to an ex-spouse, can that lower my AGI for QBI purposes?

Yes, because it lowers your taxable income.  The QBI income limit for SSTBs is determined by taxable income - not gross income.  To the extent that the alimony is deductible, and lowers taxable income,  it will serve to reduce your taxable income.
