Today's (2/4/2020) TurboTax update has fixed many of the problems with entering Spouse's Forms 1099-NEC. Delete any previously entered Forms 1099-NEC, then enter the Forms 1099-NEC under Self-employment income and expenses under the corresponding spouse's business.
Do not enter Forms 1099-NEC under Other Common Income. Entering under Other Common Income doesn't work at all.
