Do you know how to enter the Mass. bank interest exemption (2018 Form 1, line 5b)? TurboTax does not populate line 5. It displays 1099-INT interest only on line 20.
Interest earned in online banks (that is, banks with no locations in Mass.) are not counted as "Mass. bank interest." I had to go back into Federal form and enter an online bank in the section "Other Interest and Dividends to Exclude." This was reflected in my Mass. return, but did not show up in line 5a, nor did the $100 exemption in line 5b.
