There are 12 different combinations of 3 positive odd numbers that add up to 21. Namely: (There are many permutations of these combinations.) 1,1,9 1,3,17 1,5,15 1,7,13 1,9,11 3,3,15 3,5,13 3,7,11 3,9,9 5,5,11 5,7,9 7,7,7
There are several combinations of odd numbers that add up to 43. For example, 3 + 29 + 11 is equal to 43, so is 5 + 27 + 11, and many more. In fact, if you allow negative numbers, you have an infinite number of combinations.

You didn't state whether the two odd numbers to be added must be different odd numbers or whether they can be the same odd number. So I'll do both cases. Case 1: They can be the same odd number: They are all even numbers starting with 1+1=2 and ending up with 9+9=18. So you can get these 9 even numbers: 2,4,6,8,10,12,14,16,18. Case 2: They must be different odd numbers: If you require that the two single-digit odd numbers be DIFFERENT odd numbers, then you can't get 2 or 18, so you can only get these 7 even numbers 4,6,8,10,12,14,16. So the answer is either 9 or 7, depoending on whether the two odd numbers you are adding can or can't be the same odd number.

Start with the factors. Multiply combinations of three prime factors, then combinations of five, then seven, etc. All generated numbers will be guaranteed to have an odd number of prime factors.
There are 4,500 combinations.

If you mean "the sum of three odd numbers", that isn't possible. The sum of three odd numbers will always be an odd number.
There are 20 odd numbers in 40.
6 numbers are odd.
