You can just make payments based on what you estimate to owe. You don't need to fill out a form, but I believe the website prompts you to provide information about your previous tax return and how you will file in 2018 (single, married etc.) When it comes time to do taxes, you can provide your CPA with a quarterly payment transcript (also on the IRS website) to show them what you paid. They can add it to your tax form. Online tax software also should have an option to add in the amount you have already paid (I know turbotax does).
