OK, Now look at line 25 on Schedule 1. if the $4,450 also there? If so, then TurboTax DID subtract the HSA contribution from your income.
You can see Schedule 1 by looking to the left at Tax Tools (in the black column on the far left). Click on Tax Tools, then click on Tools, then in the box in the center, click on View Tax Summary, then back on the left, click on Preview My 1040. Be sure to scroll down far enough.
