Confirmed, and thank you, @Critter !
Caveat: I'm not a tax expert.
Some explanation: pension division for military retirees is an entitlement, and not alimony; as such, it is handled a bit differently: "When the pension is divided in a written instrument and the payments end no later than the death of the payee, the military retirement payments are includable in the gross income of the payee and are excludable from the payor’s income." (https://familylawyermagazine.com/articles/taxes-and-military-pensions-the-long-and-short-of-it/)
Additionally, per Carla M from TurboTax's NC call center (who discussed with their military expert), the way to do this is to claim the pension payments as "Other Reportable Income" (not 'other Wages' as I previously thought). The description is "Military Retirement Pay to ex-spouse (xxx-xx-xxxx) per USFSPA"
USFSPA is the Uniformed Services Former Spouse Protection Act
Note: TurboTax flagged the negative number when listed under 'Other income not already reported on a Form W-2 or Form 1099' -- TT was fine when instead the same negative # was used under 'Other reportable income.'
