The email refers to, other than the unemployment exclusion, if you qualify for any additional credits and deductions due to a lower AGI, you should amend your federal tax return. If the only reason you amend is the unemployment exclusion, you do not need to amend.

Per IRS, "There is no need for taxpayers to file an amended return unless the calculations make the taxpayer newly eligible for additional federal credits and deductions not already included on the original tax return."
As you go through both the Federal and State sections in TurboTax under Amendment, follow prompts. If the lower AGI qualifies you for any additional credits or deductions, you would want to amend. If the only change in refund or tax due is caused by the unemployment exclusion, you do not need to amend including both the federal and Massachusetts.
