W4 Question. Surprise!

I'm married filing jointly with 2 dependents. Last year, before the new W4 went into effect, the IRS disallowed my withholding status and removed my exceptions because they had not received my last return. My federal W/H went from $544 to $778 on my biweekly check. I cleared up the issue and the IRS sent me a letter lifting all these restrictions. Using the new W4 IRS withholding estimator. I entered all my current salary, withholding, etc. for 2020 but it is telling me I'm getting a refund over $9500. What amount do I enter and WHERE on the new W4 do I enter to get back to the previous W/H of ~$544?
