Hi folks
Stretching lines is not usually the answer, or good for the lines. This can depend on what you call stretching, running line off in arm lengths and gently stretching between your arms ( like you would a tapered leader ) can sometimes help, but stretching a long length from a fixed point can damage lines and often make the twist worse.
Line twist is frequently caused by not spooling a line correctly, especially if the line is left on the floor on the spool and then reeled in while the line is curling around that spool as it comes off in circles. There are casting faults/practices that can also cause a line to twist.
If you are putting a new line on your reel, ensure that you have something like a pencil through the plastic packaging spool and either ask somebody to hold the pencil on either side of the spool or grip the pencil ends between your knees ..... then wind the line on your reel with the reel and the plastic spool lined up in the same direction.
If you are trying to fix a line that has line twist, I find it is best to lay the line out at full length on a field if possible ( better still let it drift downstream on a river ) and then reel the line in slowly through your other hand while gripping the line between that hand's thumb and a finger with a little tension. You will see the line trying to untwist itself beyond your hand. You may have to repeat this process a few times to get rid of all the twists depending on how bad the line twist is. It can be useful to have a wee piece of damp cloth or a line cleaning pad between your thumb and finger to lower the risk of the line friction burning your fingers.
Hope this helps!
Best wishes
