Do I post the numbers from my SS COLA?

Only input information from you r 1099SA

No, that is not entered anywhere on a tax return.  You only have to enter the SSA-1099 and the amount from box 5 from the form.

No.   If you are receiving Social Security benefits the only thing you enter is the SSA1099 that was mailed to you in January.   If you do not have the SSA1099 you need to get that:
