I have my winter cover on waiting for the water to get below 60 to winterize everything. Ph is 7.2 and chlorine is around 12ppm (didn’t do a recent drop test but that’s close). Do I need to lower the chlorine level and bump up the ph or is that solid?

FC depends on your CYA level which you didn't list. For typical levels of CYA your FC is fine.

A low pH can be harmful to liners over time (brittle). Normally the pH will rise a bit as the water gets colder, but if you think the pH may fall further on its own before you close, it may be worth increasing just a little to about 7.5-7.6.
My last cya check prior to putting on the winter cover was 70 if I remember correctly. I’m writing this from work and my log book is at the house.
