Turbo Tax needs to word this differently. It's not your Massachusetts AGI you would use to determine your eligibility, it is your total income. What Turbo Tax is trying to say is, use your adjusted TOTAL income for Mass, not your federal income; which to adjust for Mass you would include dividends, ALL of your social security benefit, pension, etc. that would normally not be included in your AGI.
"For purposes of the tax credit, a taxpayer’s “total income” includes taxable income as well as exempt income such as social security, treasury bills and public pensions."
This is from "Deductions, Exemptions and 2022 'Circuit Breaker' Tax Credit"

I hope this is clear enough. I'm not a teacher/educator for a reason! Please let me know if you need me to explain anything further. Good luck 🙂
