I have been using Turbotax for several years and never bothered to cross check the figures in Federal return and MA state return. I have had significant capital losses 10 years ago. Turbotax automatically carries it over year after year. However, I just noticed that it never included these losses in MA state tax. This year I have some decent capital gains which were offset by the carryover losses. When I noticed that I am paying quite a bit of MA tax I cross checked the figures. It is because of the capital gains this year and it is not showing the carryover losses. It looks like in the past several years Turbotax has been doing this and I may have been paying more MA tax than I should. How do I rectify this?
