The 2025 W2 now includes code "II - Medicaid waiver..." in Box 12a to indicate this situation. With that indicated, TurboTax would not show the Medicaid waiver checkbox among the uncommon situations. This is a correct behavior. However, TurboTax still does not allow eFile when the W2 Box 1 is zero. So entering $1, $2, $3, etc. still seems necessary to both all eFile AND avoid the complaints about duplicate W2.
