Could enlarged nasal turbinates and deviated nasal septum cause sleep apnea? Had PNR and was told that sinuses are good. I don't snore.

Yes. these findings can contribute to underlying OSA which is why it is something we look for during a sleep evaluation.
Deviated septum. Nasal obstruction can contribute to sleep apnea, get a sleep study and have your nose evaluated by a board certified otolaryngologist,
Nasal swelling. What you describe could interfere with your sleep. I doubt it would cause sleep apnea. You may want to see an ENT for further evaluation.
