Hi! To be clear, I still used Turbotax to complete the package. After paying the price, it allows me to print out a deck of papers, but I had to mail this package. So every deductions/tax credits were computed by TT, just without the option to e-file.
Edit: In the corresponding screen where they doubled your transferred wages, they will ask you if the number is correct. Say it's not correct, and then it will prompt you if you want to transfer only the MA part. But then it will say you'll be ineligible for e-filing. Everything else proceeds as usual, and once you complete the package, pay the TT price and then print out the documents to be mailed. I could never figure out how to do it myself without tax softwares or help from accountants.
