Here you go. I did it in 14 steps. I don't know if it can be done in fewer.

I will label the 3 jars j1, j2 and j3.

j1 holds 19 litres

j2 holds 13 litres

j3 holds 7 litres

I am starting off by filling j1 full (19 litres) and putting the remaining litre in j2, so I have this makeup

j1 = 19

j2 = 1

j3 = 0

Step 1 Fill j3

j1 = 12

j2 = 1

j3 = 7

Step 2 put j3 in j2

j1 = 12

j2 = 8

j3 = 0

Step 3 fill j3

j1 = 5

j2 = 8

j3 = 7

Step 4 fill j2 with j3

j1 = 5

j2 = 13

j3 = 2

Step 5 put j2 into j1

j1 = 18

j2 = 0

j3 = 2

Step 6 put j3 into j2

j1 = 18

j2 = 2

j3 = 0

Step 7 fill j3

j1 = 11

j2 = 2

j3 = 7

Step 8 put j3 into j2

j1 = 11

j2 = 9

j3 = 0

Step 9 fill j3

j1 = 4

j2 = 9

j3 = 7

Step 10 fill j2 with j3

j1 = 4

j2 = 13

j3 = 3

Step 11 put j2 in j1

j1 = 17

j2 = 0

j3 = 3

Step 12 put j3 into j2

j1 = 17

j2 = 3

j3 = 0

Step 13 fill j3

j1 = 10

j2 = 3

j3 = 7

Step 14 put j3 into j2

j1 = 10

j2 = 10

j3 = 0

j3 = 7

Step 10 fill j2 with j3
