There are no four odd numbers that will add up to nineteen.
The sum of any four odd numbers will never be equal to an odd number.
You cannot add 4 odd NUMBERS to make an odd number, so you have to think constructively...eg 1 + 3 + 15 = 19. There are other similar solutions...
If you are wanting to add odd numbers to get 399, it won't work. If you are wanting to multiply to get 399, it is 19 x 21.

You can add any one of 13, 15, 17, 19 and 21.

It cannot make the sum because: if the numbers are in odd quantity there sum is always a odd number
17, 19, 21 and 23.
There have to be an even number of odd numbers in each group, and each group must have more than two odd numbers (since 19 + 17 is only 36); thus there must be four in one group and six in the other. There are many ways to get four odd numbers to add up to to 50; for example, you could take 1, 13, 17 and 19. The remaining six odd numbers will then also add up to 50.
