I discovered (fortunately!) that my 2023 federal capital losses were not automatically plugged into my MA State Return by the program to offset the 2024 gains... Hence, my taxes due for the state were way too high. Also, the comparison of the prior year's State taxes paid with the current year's tax liability did not happen in the program so the exemption to avoid an under-payment penalty on the state return was not claimed. Those two little issues ended up showing that I owed $10K more taxes to the state than I should. Not Good! Be careful out there.
