What does an IRS CP14 notice mean, and what should I do first?

I received an IRS CP14 balance due notice and the deadline on the letter feels tight. Before I call anyone or pay, I want to understand what this notice actually means. From what I have gathered so far: 1. CP14 usually means the IRS believes you owe a balance for a tax year. 2. The letter should list the tax year, amount due, and a payment due date. 3. Ignoring it can lead to more notices and penalties. What steps did you take first when you got a CP14? Did you verify the amount against your return, set up a payment plan, or request more time?
