Summary
Entacapone may modestly raise finerenone exposure if it acts as a weak CYP3A4 inhibitor, which could increase the risk of hyperkalemia and reduced renal function. The effect is theoretical and likely small.
What this interaction means in plain words
Carbidopa-entacapone-levodopa and Finerenone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Why it happens
Possible weak inhibition of CYP3A4-mediated finerenone metabolism by entacapone; clinical inhibition is not well established.
