The requirements you spell out do not enable the derivation of a normal magic square. Normal squares have 9, 16, 25, 36, etc. squares using the given digits once. For instance
8--1--6
3--5--7
4--9--2
all rows, columns and diagonals adding to 15 or

1--15--14--4
12--6--7--9
8--10--11--5
13--3--2--16
all rows, columns and diagonals adding to 25.

While your square appears to have only 12 digits, I think you would be hard pressed to have them arranged so that they sum to 26 when the normal magic square using 16 digits of 1 through 16 adds to only 25. If a digit can be used more than once, perhaps that opens the door to possibilities. It would appear that you have a guess and check game to play here.

From 1 to 12, we have six pairs with sum of 13. (1,12), (2, 11), (3, 10), (4, 9), (5, 8) and (6, 7). Sum of two pairs will be 26. Therefore, playing around with these pairs. Here is the answer:

1 9
5 10 2 7
8 3 11 6
12 4

Re-arrange number again

1 -------------- 9
5 -- 10 -- 2 -- 7
8 -- 3 -- 11 -- 6
12 ------------- 4

1 -------------- 9
8 -- 10 -- 2 -- 6
5 -- 3 -- 11 -- 7
12 ------------- 4
