As I'm going thru the state portion of my return with Turbo Tax Deluxe I come upon "Pension Adjustments-Federally Taxable". I entered from my 1099R the amount that's listed in block 2 a :Taxable amount into the blank box "non-taxable Massachusetts Pension". My 1st question am I doing it correctly? Then it indicates the following message: After manually entering an exclusion amount above, you will not be eligible to electronically file your Massachusetts tax return. My question to that is why?
