It seems TT has a lot of problems dealing with Part Time MA returns. I had a nightmare last year trying to properly allocate excluded dividends for US Government Obligations on the MA return between two states. I also spent over an hour on the phone with support who agreed there was a problem but could not fix it.
The other state was fine but the software was broken for MA. I ended up having to get a refund for the TT S/W and filed with another tax program. Unfortunately for TT, I got a taste for much less expensive s/w that actually worked and I had been using TT since the early 2000's.
Glad you figured it out.
