smurfy let me give you my thought s on Bronchiectasis (lung damage)
Depending upon the amount of lung damage, it could be a big deal or no big deal, you could live 50 years with minimal bronchiectasis.
The main symptoms are shortness of breath either on exercise or at rest, productive cough with mucous, coloured or colourless and a predisposition for chest infections.
From what you describe, in my opinion, your present symptoms are are due to Covid, however, do not be complacent as the colour of your sputum and your breathlessness could soon change and depending upon your general oall feeling of well being become a bigger deal necessitating antibiotics.
As for now, your symptoms are due to Covid and not bronchiectasis.
