Getting a federal refund, why estimated tax?

Just completed my 2022 federal and state tax returns and went through to view the printed form before filing. I’m getting a refund for both federal and state, but my preview form shows estimated tax payments of $300 per quarter. What’s up with this?  
Both myself and my husband are employed, there have been no changes in our tax situation, and we’ve gotten a refund for the last 5+ years. Why would we need to pay estimated taxes? Something seems wonky.

thanks for any help or direction you can provide
