Since you want to start at two, I decided to use the \$\overline{Q_B}\$ as output instead of \$Q_B\$ so that the reset state starts at the right place.
$$\begin{array}{c|c|c} \text{Beginning State} & \text{Ending State} & \text{Excitation}\\\\ {\begin{array}{cccc} Q_D & Q_C & \overline{Q_B} & Q_A\\\\ 0&0&1&0\\ 0&0&1&1\\ 0&1&0&0\\ 0&1&0&1\\ 0&1&1&0\\ 0&1&1&1\\ 1&0&0&0\\ 1&0&0&1\\ 1&0&1&0\\ 1&0&1&1\\ 1&1&0&0\\ 0&0&0&0\\ 0&0&0&1\\ 1&1&0&1\\ 1&1&1&0\\ 1&1&1&1\\ \end{array}} & {\begin{array}{cccc} Q_D & Q_C & \overline{Q_B} & Q_A\\\\ 0&0&1&1\\ 0&1&0&0\\ 0&1&0&1\\ 0&1&1&0\\ 0&1&1&1\\ 1&0&0&0\\ 1&0&0&1\\ 1&0&1&0\\ 1&0&1&1\\ 1&1&0&0\\ 0&0&1&0\\ x&x&x&x\\ x&x&x&x\\ x&x&x&x\\ x&x&x&x\\ x&x&x&x\\ \end{array}} & {\begin{array}{cccc} T_D & T_C & T_B & T_A\\\\ 0&0&0&1\\ 0&1&1&1\\ 0&0&0&1\\ 0&0&1&1\\ 0&0&0&1\\ 1&1&1&1\\ 0&0&0&1\\ 0&0&1&1\\ 0&0&0&1\\ 0&1&1&1\\ 1&1&1&0\\ x&x&x&x\\ x&x&x&x\\ x&x&x&x\\ x&x&x&x\\ x&x&x&x\\ \end{array}} \end{array}$$
I think I have the above table written, correctly. (Do check it over, though. I make mistakes, like everyone else.) If you take your outputs as I suggested, that table should cover it.
The last column is the Excitation that you need for each of your TFF-wired JK FF. (I just mean that you've tied J and K together.) The last column represents the value that should be applied to the JK-pair wired together for that FF. You already are doing something like that, so you are aware of the idea. So if you look over the last column you can see a 0 when you don't want to change the state of that FF and a 1 when you do want to change its state (toggle it.)
Looking over the table, does all this make sense?
Once you have that much, all you need to do is to lay out four K-map tables.
$$ \begin{array}{rl} \begin{smallmatrix}\begin{array}{r|cccc} T_D&\overline{Q_B}\:\overline{Q_A}&\overline{Q_B}\: Q_A&Q_B \:Q_A&Q_B \:\overline{Q_A}\\ \hline \overline{Q_D}\:\overline{Q_C}&0&0&0&0\\ \overline{Q_D}\:Q_C&0&0&0&0\\ Q_D\: Q_C&1&0&0&1\\ Q_D\:\overline{Q_C}&0&0&0&0 \end{array}\end{smallmatrix} & \begin{smallmatrix}\begin{array}{r|cccc} T_C&\overline{Q_B}\:\overline{Q_A}&\overline{Q_B}\: Q_A&Q_B \:Q_A&Q_B \:\overline{Q_A}\\ \hline \overline{Q_D}\:\overline{Q_C}&0&1&0&0\\ \overline{Q_D}\:Q_C&0&1&0&0\\ Q_D\: Q_C&0&0&0&1\\ Q_D\:\overline{Q_C}&0&1&0&0 \end{array}\end{smallmatrix}\\\\ \begin{smallmatrix}\begin{array}{r|cccc} T_B&\overline{Q_B}\:\overline{Q_A}&\overline{Q_B}\: Q_A&Q_B \:Q_A&Q_B \:\overline{Q_A}\\ \hline \overline{Q_D}\:\overline{Q_C}&0&1&0&0\\ \overline{Q_D}\:Q_C&0&1&1&0\\ Q_D\: Q_C&0&0&1&1\\ Q_D\:\overline{Q_C}&0&1&1&0 \end{array}\end{smallmatrix} & \begin{smallmatrix}\begin{array}{r|cccc} T_A&\overline{Q_B}\:\overline{Q_A}&\overline{Q_B}\: Q_A&Q_B \:Q_A&Q_B \:\overline{Q_A}\\ \hline \overline{Q_D}\:\overline{Q_C}&1&1&1&1\\ \overline{Q_D}\:Q_C&1&1&1&1\\ Q_D\: Q_C&1&1&1&0\\ Q_D\:\overline{Q_C}&1&1&1&1 \end{array}\end{smallmatrix}\end{array} $$
I'm in a rush (appointment ahead), so the above table may have errors. But I think I got it right. You can use those tables (fixed for errors you may catch) to develop the logic required. (Actually, I see errors already -- I'll fix them.)
Does that make sense?
