Stated plan

Play Qc1 to block the promotion square and force a queen trade, eliminating Black's dangerous counterplay.

Resolves to f4c1 · −2368cp

Reasoning

Black threatens ...c1 promoting a second queen, which would be devastating with the queen already on a1 defending c1. White's queen can occupy c1 directly, and since Black's queen on a1 attacks c1, this forces a trade of queens, neutralizing the promotion threat and simplifying into a favorable endgame.
