Q. How do I remove those wages using Turbo Tax (TT)?
A. TurboTax does that automatically. After entering your W-2, you will reach a screen titled "Let's check for uncommon situations". Check the box "non taxable medicare waiver payments that qualify as difficulty of care payments"
Q. Should I enter the amount from box 1 as federal wages.
A. Yes. As stated, TT does the required adjustment

The IRS has provided a place to deduct (line 8s of Schedule 1) the nontaxable income (but still allow you to claim the Earned Income credit based on that income)
