My wife and I also made contribution to our grandson's MA 529 Plan. In preparation of filing 2019 tax, I checked 2018 MA Tax form. The instruction for Line 18 of Form Y, Other Deductions, states that "A deduction is available for purchases of or contributions made to an account in a pre-paid tuition program or a college savings program established by the Commonwealth. The deduction is capped at $1,000 for a single person, married filing separate, or head of household and $2,000 for a married couple filing a joint return." Yet, my 2018 MA tax shows no deductions for our contribution. I have to pay closer attention to this when I file for 2019. I have to also investigate whether there is any way to claim the deduction retroactively. If TurboTax did not prmpt me for this deduction in 2018, I hope TuboTax fixed this problem.
