I’m a personal caregiver for my son. I live with him. My income is supposed to be tax free?

[HeatherLove]

How do I put in here

You are correct.  The income is not taxed on the Federal income tax return.

The complication is that your tax-exempt Medicaid waiver payments from in-home supportive services (IHSS) may be on a W-2, 1099, or no form at all, depending upon where you live.

How the income is reported in TurboTax depends upon how (or whether) the income was reported to you.  See this TurboTax Help.
